Types of Samadhi – A Comprehensive Guide

What is Samadhi?

Samadhi is often referred to as the pinnacle of yogic practice, a state of deep, meditative absorption where the mind becomes still and merges with the object of focus.

Yet, for many, this ethereal term remains elusive and mystifying. What exactly is Samadhi, and more importantly, how does one attain it?

Classical Types of Samadhi According to Patanjali's Yoga Sutras

Introduction to Patanjali's Yoga Sutras

Before diving into the types of Samadhi, it's important to understand the foundational text that outlines them: Patanjali's Yoga Sutras. In the context of the Eight Limbs of Yoga, Samadhi is the final limb.

Compiled over two millennia ago, the Yoga Sutras serve as a comprehensive guide to the philosophy and practice of yoga. Patanjali identifies different stages of meditation, culminating in various forms of Samadhi.

Understanding Samprajñata and Asamprajñata Samadhi

These are two broad categories of Samadhi described in the Yoga Sutras.

  • Samprajñata Samadhi: Also known as "cognitive Samadhi," this is a state where some form of cognition or understanding remains. Under this category, several subtypes exist, which include Savitarka, Nirvitarka, Savichara, and Nirvichara.
  • Asamprajñata Samadhi: Also called "non-cognitive Samadhi," this is a state where all cognitive processes cease. It is considered to be the ultimate state, beyond which lies liberation (moksha).

The Four Subtypes of Samprajñata Samadhi: Exploring the Layers of Cognitive Focus


Samprajñata Samadhi, a type of meditative concentration as outlined in Patanjali's Yoga Sutras, has four distinct subtypes. These subtypes serve as progressive stages of depth and focus, guiding practitioners towards higher states of consciousness. Let's dive into each subtype to understand their unique characteristics, applications, and the path from one to the next.

Savitarka Samadhi: Gross Cognitive Focus


Savitarka Samadhi is often considered the starting point for practitioners who are venturing into the realm of Samadhi, as described in Patanjali's Yoga Sutras. In this state, the meditator's focus is on gross or physical objects. This form of Samadhi is characterized by the presence of cognition, meaning thoughts and mental activities still occur, albeit in a controlled manner. Let's dive into its complexities, practice tips, and its importance on the path of self-realization.

Definition and Characteristics

Savitarka Samadhi is essentially a state of concentrated focus on a gross object. Gross objects can be material things like a candle flame, a flower, or even an image of a deity. In this state, mental activities are present but contained. The mind isn't entirely silent; instead, it's focused, coherent, and in tune with the object of meditation.

Characteristics commonly associated with Savitarka Samadhi include:

  • Concentration: High level of mental focus on a single object
  • Presence of Thought: Unlike deeper states of Samadhi, thoughts are still present but not distracting
  • Sensory Awareness: External sensory information may be present but not disturbing the focus
  • Initial Stillness: A state of early mental quietude, setting the stage for deeper forms of Samadhi

Nirvitarka Samadhi: Transcending Gross Cognitive Focus

Nirvitarka Samadhi takes the practitioner a step further in the journey of achieving higher states of consciousness. Unlike Savitarka Samadhi, where gross objects serve as the focus, Nirvitarka allows the mind to go beyond the surface level of perception. In this form of Samadhi, the practitioner transcends thoughts related to the object of focus, entering a more refined state of pure awareness.

Definition and Characteristics

In Nirvitarka Samadhi, the mind reaches a state where it is no longer preoccupied with the object's attributes, meaning, or connotations. The focus becomes purer, free from mental noise and distractions.

Characteristics commonly associated with Nirvitarka Samadhi include:

  • Pure Focus: The focus is intense, but devoid of mental commentary or analysis.
  • Transcendental Awareness: The meditator becomes aware of the object as an essence, without categorization or labeling.
  • Absence of Thought Waves: Unlike Savitarka Samadhi, the mental fluctuations are significantly reduced, if not entirely absent.
  • Subtle Joy: A sense of inner peace and happiness often accompanies this state, indicating alignment with the object of focus at its most fundamental level.

Savichara Samadhi: Subtle Cognitive Focus

Savichara Samadhi takes you into the realm of subtler aspects of consciousness. Building upon the advancements made in Nirvitarka Samadhi, Savichara introduces a focus on subtle objects, which could include abstract concepts or intangible elements like sound or light.

Definition and Characteristics

In Savichara Samadhi, the meditator directs their awareness toward subtle objects that are not materially manifest. These could include sensations, energies, or abstract philosophical concepts. The mind begins to focus at a subtler level, going beyond the gross physical aspects of reality.

Key characteristics of Savichara Samadhi include:

  • Subtle Object Focus: The object of concentration is subtle rather than gross.
  • Enhanced Perception: An increased sensitivity to perceive things at a deeper, subtler level.
  • Reduced Cognitive Activity: Unlike earlier states, there's less mental chatter as you go deeper into concentration.
  • Clarity and Insight: Insights may occur that open up new dimensions of understanding.

Nirvichara Samadhi: Beyond Cognitive Focus

Nirvichara Samadhi is often seen as the culmination of the cognitive-focused types of Samadhi. It represents a state where even subtle thoughts are transcended, and a deeper level of inner silence is achieved. This form of Samadhi paves the way for further advanced states and is critical for deepening one's meditative practice.

Definition and Characteristics

Nirvichara Samadhi is defined as a state devoid of even the subtlest form of cognitive focus. It involves transcending not only gross objects but also subtle concepts or sensations, reaching a state of pure consciousness.

Key characteristics include:

  • Absence of Cognitive Focus: Unlike previous stages, Nirvichara Samadhi involves no focus on any object, subtle or gross.
  • Pure Consciousness: The practitioner's awareness is rooted in a pure, undifferentiated consciousness.
  • Deep Inner Silence: An intense inner silence and peace characterize this state.
  • Non-Dual Awareness: A sense of non-duality or unity with all existence may be experienced.

Asamprajñata Samadhi: Beyond Cognitive Distinctions

Asamprajñata Samadhi is a state of meditative absorption where there is no object of focus, no thought, and no cognitive processes at work. This form of Samadhi is characterized by the absence of attributes and distinctions; the meditator is absorbed in an undifferentiated state of consciousness that transcends the dualistic notions of self and other.

Historical Background of Asamprajñata Samadhi

Asamprajñata Samadhi is rooted in ancient Indian spiritual traditions and is prominently mentioned in Patanjali’s Yoga Sutras. It is considered one of the highest forms of Samadhi and has been discussed by various sages, philosophers, and yogis throughout history.

Sources of Understanding

Patanjali’s Yoga Sutras serve as a foundational text for understanding Asamprajñata Samadhi. Other texts like the Upanishads and the Bhagavad Gita also provide insights into this form of Samadhi. Modern spiritual teachers, such as Ramana Maharshi and Sri Nisargadatta Maharaj, have provided contemporary perspectives on the state through their teachings.

Practices Leading to Asamprajñata Samadhi

Asamprajñata Samadhi is typically achieved after extensive practice of lower forms of Samadhi and other yogic disciplines. Meditation, mindfulness, pranayama, and various ascetic practices serve as stepping stones to this elevated state of consciousness.

Relationship with Earlier Types of Samadhi

In the context of Patanjali’s classification, Asamprajñata Samadhi is understood as a higher form of Samadhi compared to Samprajñata Samadhi and its subtypes (Savitarka, Nirvitarka, Savichara, Nirvichara). While the latter involve focus and cognitive processes, Asamprajñata Samadhi transcends all form and thought. It is the state where even the subtlest form of individuality dissolves, making it closely related to Nirvikalpa Samadhi, albeit with subtle experiential differences.

In Asamprajñata Samadhi, the distinctions between the meditator, the process of meditation, and the object of meditation merge into a single unity. In this respect, it serves as the culmination of the spiritual journey, representing an ultimate union with the divine or the absolute.

Key characteristics include:

  • Complete Loss of Dualism: There's no sense of 'I' or 'Other,' only a unified field of consciousness.
  • Indescribable Peace: Words can hardly capture the profound sense of peace and bliss.
  • Direct Intuition: Without the interference of thought, direct knowing or intuition is possible.
  • Absence of Time and Space: The yogi transcends all limitations of time and space.

Historical Context and Sources of Understanding for Advanced Samadhi Types

Understanding the evolution and historical framework of Samadhi concepts is essential for grasping their depth and significance. While Patanjali's Yoga Sutras have been a cornerstone in explaining the classical types of Samadhi, our understanding of the more advanced types often draws from a larger corpus of spiritual texts and traditions.

Sahaja Samadhi: The Natural State

Sahaja Samadhi is often referred to as the "natural state" of being or "effortless awareness." It is a state where the meditator is simultaneously aware of the inner Self and the external world without a sense of conflict or duality. In Sahaja Samadhi, one does not withdraw from the senses or the world but exists in a state of pure awareness that permeates all aspects of life.

Historical Roots of Sahaja Samadhi

The concept of Sahaja is ancient and can be traced back to various spiritual traditions like Hinduism, Buddhism, and Taoism. In Hinduism, it gained prominence in Advaita Vedanta through the teachings of sages like Ramana Maharshi and Nisargadatta Maharaj. In Buddhism, it is similar to the concept of Rigpa, or nondual awareness, as found in Dzogchen teachings.

Sources of Understanding

The "Ashtavakra Gita," a classical Hindu text, elaborates on the natural state of being in the form of a dialogue between King Janaka and the sage Ashtavakra. More recently, the teachings of modern-day spiritual leaders like Eckhart Tolle have brought the concept into mainstream consciousness.

Practices Leading to Sahaja Samadhi

In the Advaita Vedanta tradition, self-inquiry or "Atma Vichara" is often recommended as the direct path to Sahaja Samadhi. Practices like mindfulness and presence can also guide one towards this state.

Differences and Similarities with Earlier Types of Samadhi

Unlike Samprajñata Samadhi, where there is an object of meditation, or Asamprajñata Samadhi, where even the subtlest object dissolves, Sahaja Samadhi is a state of spontaneous, effortless awareness. It can be considered an advanced stage where the distinctions between subject and object, internal and external, dissolve completely. In a way, it can be seen as an ultimate goal, where the other forms of Samadhi prepare the practitioner to effortlessly sustain this 'natural state'.

Nada Samadhi: The Sound of Silence

Nada Samadhi is a unique form of meditative absorption focused on the inner, subtle sound or "nada." This sound isn't one that comes from external sources, but rather, it is a spiritual or metaphysical sound that is heard during deep meditation.

The practitioner focuses on this internal sound, which can manifest as buzzing, humming, or even music, until they become one with it, leading to a state of Samadhi.

Historical Roots of Nada Samadhi

The practice of Nada Yoga, which involves concentrating on internal sounds, has ancient origins and is mentioned in several Hindu scriptures, including the "Hatha Yoga Pradipika." The concept also finds mention in Buddhist and Sikh traditions, illustrating its widespread influence across various spiritual systems.

Sources of Understanding

The "Hatha Yoga Pradipika," one of the seminal texts on Hatha Yoga, discusses Nada Yoga in detail, describing the various sounds one might encounter and the process of meditating on them. Modern-day teachers and spiritual communities have also contributed to an expanded understanding of this form of Samadhi.

Practices Leading to Nada Samadhi

Concentration on the inner sound often begins after one has mastered certain aspects of pranayama, or breath control. As the mind becomes still, the subtle internal sounds may become apparent. Practitioners are taught to focus on these sounds, using them as an object of meditation, leading to deeper states of inner silence and eventually Nada Samadhi.

Differences and Similarities with Earlier Types of Samadhi

In Nada Samadhi, like in Samprajñata Samadhi, there is an object of focus—the internal sound.

However, as the meditation deepens, this sound may no longer be perceived as separate from the self, bringing it closer to the objectless state of Asamprajñata or even Sahaja Samadhi.

The focus on internal sound makes Nada Samadhi distinct but complementary to other forms of Samadhi, serving as another pathway to the same ultimate goal of unified consciousness.

Laya Samadhi: Dissolution into the Divine

Laya Samadhi is a state of meditative absorption where individual consciousness dissolves into universal or divine consciousness.

The term "Laya" translates to "dissolution" or "absorption," and in this state, the practitioner experiences a loss of individual self, merging into the larger, infinite consciousness.

This form of Samadhi transcends dualities and limitations, offering a profound sense of unity and oneness.

Historical Context

Laya Yoga, from which the concept of Laya Samadhi is derived, is a Tantric practice that has its roots in ancient Hindu and Buddhist spiritual traditions. It is often connected to Kundalini Yoga, as both aim to merge individual consciousness with universal consciousness through the awakening of the Kundalini energy.

Sources of Understanding

Key texts that describe Laya Yoga and Laya Samadhi include the "Yoga Kundalini Upanishad" and the "Shiva Samhita," among others. These texts detail the practices and philosophical background necessary for attaining Laya Samadhi.

Practices Leading to Laya Samadhi

Laya Yoga employs advanced techniques that include specialized pranayama, mudras, and bandhas to awaken and channel Kundalini energy through the chakras.

As this energy ascends to the crown chakra, practitioners may experience Laya Samadhi. It's crucial to approach this practice with caution and preferably under the guidance of an experienced teacher, given its potent and transformative nature.

Relationship with Earlier Types of Samadhi

Laya Samadhi is often considered an advanced form of Samadhi, similar in many respects to Asamprajñata Samadhi.

Both types involve a dissolution of the ego and a merging with universal consciousness. However, Laya Samadhi specifically involves the energetic pathways and chakras, making it a more focused and specialized practice.

Whereas the Samprajñata types involve an object of meditation, in Laya Samadhi the object dissolves, leaving only pure consciousness. This makes it more akin to Asamprajñata Samadhi, where there is also no object of focus.

Savikalpa Samadhi: A State of Meditative Absorption with Attributes

Savikalpa Samadhi is a state of deep meditative absorption where the practitioner remains aware of distinctions such as the meditator, the act of meditation, and the object of meditation.

In this state, thoughts and perceptions are not entirely silenced but are transformed into a harmonious flow that supports the meditative experience.

The term "Savikalpa" means "with differences" or "with attributes," which suggests that in this state, one's individuality is maintained even while diving deep into meditation.

Historical Background

The concept of Savikalpa Samadhi is rooted in Advaita Vedanta and is often discussed in the context of Jnana Yoga, the yoga of knowledge. It appears in classic scriptures like the "Mandukya Upanishad" and is elaborated upon by philosophers such as Adi Shankaracharya.

Sources of Understanding

Texts that detail the process of reaching Savikalpa Samadhi include the "Viveka Chudamani" and the works of modern-day mystics and yogis like Paramahansa Yogananda, who spoke extensively about this type of Samadhi in his teachings and writings.

Practices Leading to Savikalpa Samadhi

The pathway to Savikalpa Samadhi often involves intense concentration (Dharana) and meditative focus (Dhyana). These practices help to quiet the mind, making it receptive to deeper states of awareness.

Techniques might include mantra meditation, focused breathing exercises, or analytical meditation that probes the nature of self and existence.

Relationship with Earlier Types of Samadhi

Savikalpa Samadhi is closely related to Samprajñata Samadhi, specifically its subtler forms like Nirvichara Samadhi. Both involve a form of contemplative absorption where an object or focus remains.

However, while Samprajñata Samadhi is often tied closely to the Yoga Sutras and its eightfold path, Savikalpa Samadhi has its primary roots in Advaita Vedanta and is often approached through the path of Jnana Yoga.

What distinguishes Savikalpa from Asamprajñata or other forms is the retention of dualistic awareness. In Savikalpa Samadhi, the practitioner remains cognizant of their own existence and the existence of the Divine, enjoying a harmonious but distinct relationship between the two.

Nirvikalpa Samadhi: The Pinnacle of Non-Dual Awareness

What is Nirvikalpa Samadhi?

Nirvikalpa Samadhi is considered the ultimate state of meditative absorption, characterized by the complete absence of individual consciousness and the experience of pure, undifferentiated awareness.

In this state, the sense of individuality, duality, and even the awareness of being in a state of Samadhi dissolve into a unified experience of Absolute Reality.

Historical Background

The concept of Nirvikalpa Samadhi has its roots in ancient Indian philosophical systems like Advaita Vedanta and is mentioned in a range of texts such as the "Upanishads," the "Bhagavad Gita," and the works of sage Patanjali.

It's also frequently commented upon by notable spiritual figures such as Adi Shankaracharya and Ramana Maharshi.

Sources of Understanding

Some of the key scriptural references to Nirvikalpa Samadhi can be found in the "Mandukya Upanishad," the "Viveka Chudamani," and other Advaitic texts. Moreover, contemporary spiritual leaders like Sri Ramakrishna and Swami Vivekananda have elaborated upon the state through their teachings and personal experiences.

Practices Leading to Nirvikalpa Samadhi

Attaining Nirvikalpa Samadhi is considered the culmination of years, if not lifetimes, of spiritual practice. Various forms of intense meditation (Dhyana), self-inquiry (Atma-Vichara), and other advanced yogic techniques aim to prepare the practitioner for this ultimate state.

Relationship with Earlier Types of Samadhi

Nirvikalpa Samadhi is often considered the zenith of Asamprajñata Samadhi. While Samprajñata and its subtypes involve some form of object or focus in meditation, Asamprajñata Samadhi and particularly Nirvikalpa Samadhi, involve the cessation of all cognitive activity and dualistic thought.

It is the point at which the meditator and the object of meditation become one, devoid of any attributes or qualifications.This is in contrast with Savikalpa Samadhi, where the individual still retains a sense of individuality.

In Nirvikalpa Samadhi, even this subtlest sense of duality vanishes, leading to an ineffable experience often described as the state of "being, consciousness, and bliss" (Sat-Chit-Ananda).

Kevala Nirvikalpa Samadhi: The Pinnacle of Non-Dual Awareness

Kevala Nirvikalpa Samadhi is considered one of the highest states of Samadhi in various yogic and Vedantic traditions. In this state, the practitioner experiences a complete dissolution of the ego and individuality, entering into a non-dual, formless awareness.

Unlike temporary states of Nirvikalpa Samadhi, Kevala Nirvikalpa is a more enduring state where one remains immersed in non-dual consciousness even while engaging with the external world.

Historical Background

The concept of Kevala Nirvikalpa Samadhi has its roots in the ancient Indian philosophies of Advaita Vedanta and Yoga. The term is often associated with renowned spiritual masters such as Shankaracharya, Ramana Maharshi, and Sri Nisargadatta Maharaj, among others, who have spoken or written about this elevated state of being.

Sources of Understanding

The foundational understanding of Kevala Nirvikalpa Samadhi comes from the Upanishads, Bhagavad Gita, and the works of Advaita Vedanta philosophers.

Modern spiritual teachers and texts also offer valuable insights into this state, blending ancient wisdom with contemporary experiences.

Practices Leading to Kevala Nirvikalpa Samadhi

Reaching this exalted state often involves years of disciplined practice, typically starting with simpler forms of meditation and progressing through the various types of Samadhi discussed earlier.

Techniques such as self-inquiry (Atma Vichara), intense devotion (Bhakti), and complete surrender to the divine will (Ishwara Pranidhana) are often cited as effective pathways.

Relationship with Earlier Types of Samadhi

Kevala Nirvikalpa Samadhi is generally considered the culmination of the yogic journey, transcending even Asamprajñata Samadhi in its depth and permanence.

While Asamprajñata Samadhi is a state where all cognitive distinctions disappear, Kevala Nirvikalpa allows one to operate in the world without losing the state of non-dual awareness. In that sense, it is the ultimate fulfillment of the potential inherent in all earlier forms of Samadhi.

Theological and Philosophical Implications

In Kevala Nirvikalpa Samadhi, the practitioner experiences the ultimate reality, often described as Brahman in Vedantic philosophy.

This is a state of pure being, beyond all forms and categories, often described as "Sat-Chit-Ananda" (Existence-Consciousness-Bliss). In this state, all questions, doubts, and dualities are resolved, and what remains is the pure, unchanging reality.

Types of Samadhi in Bhakti and Devotional Paths: The Union of Love and Divinity

While the classical Yoga Sutras and Advaita Vedanta philosophies offer profound insights into the meditative and cognitive dimensions of Samadhi, Bhakti yoga and other devotional paths provide a different perspective on this exalted state.

In Bhakti, Samadhi is not just a cognitive union with the ultimate reality but is deeply emotional, characterized by pure, unconditional love for the Divine.

Historical Context

Bhakti as a form of devotion has deep roots in Indian spiritual traditions, and it found expression in various religious movements and saints across India.

Think of the Alvars and Nayanars in Tamil Nadu, Sant Eknath and Tukaram in Maharashtra, and Mirabai in Rajasthan. Their devotional hymns and teachings often describe states of Samadhi achieved through intense love and devotion.

Sources of Understanding

The primary scriptures in this path include texts like the Srimad Bhagavatam, Ramcharitmanas, and various hymns and verses by Bhakti saints. These scriptures elucidate different types of Samadhi achieved through devotion.

Bhava Samadhi: Emotional Ecstasy

In Bhava Samadhi, the devotee becomes so engrossed in the divine emotion that they lose all awareness of the external world. It's like a spiritual trance where the devotee feels oneness with the Divine.

Prema Samadhi: The Samadhi of Divine Love

In this state, the devotee’s love for the Divine is so intense that they experience an inseparable unity with their chosen deity or form of God. It is the epitome of the 'Madhurya' or sweetness aspect of God, often cited in the context of Krishna Bhakti.

Seva Samadhi: Union through Selfless Service

Seva Samadhi is achieved when a devotee finds divine union in selfless service to God or humanity. The act of service becomes a meditation, where actions are no longer driven by personal will but are seen as offerings to the Divine.

Relationship with Earlier Types of Samadhi

The Bhakti path to Samadhi is not necessarily exclusive from other paths. In fact, many Bhakti saints have expressed states similar to Nirvikalpa or Sahaja Samadhi but viewed through the lens of divine love. The idea is that irrespective of the path—Bhakti, Jnana, or Dhyana—the destination is the same: a state of ultimate unity and identification with the Divine.

Samadhi Types in Buddhist Traditions: The Middle Way to Enlightenment

While Samadhi finds its roots in the Hindu yogic tradition, its significance is equally pronounced in Buddhist philosophy. Buddhism offers unique perspectives on Samadhi, framed around the goal of achieving enlightenment and liberation from suffering.

Historical Context

Samadhi is deeply integrated into the practice of Buddhism, starting from the time of the Buddha himself. Buddha's enlightenment beneath the Bodhi Tree involved intense meditation and likely some form of Samadhi. Many of the early Buddhist texts, like the Pali Canon and Mahayana sutras, discuss different states of concentrated focus and awareness.

Primary Texts and References

Key sources for understanding Samadhi in Buddhism include the Tripitaka, specifically the Sutta Pitaka and the Abhidhamma Pitaka, as well as Mahayana texts like the Prajnaparamita Sutras and Zen literature.

Access Concentration (Upacara Samadhi)

This is a preliminary form of concentration that sets the stage for deeper states. Though not full Samadhi, it serves as a critical stepping stone and is often seen as the doorway to Jhanic states.

Jhana Samadhi

The concept of Jhana (or Dhyana in Sanskrit) represents deeply concentrated meditative states that progressively deepen. There are usually four or eight Jhanas described, each with unique qualities of focus, joy, and equanimity.

Vipassana Samadhi

In this form, Samadhi is cultivated through the practice of insight meditation or Vipassana. Here, the meditator is not just focused but also gains deep insights into the nature of reality, particularly the Three Marks of Existence: impermanence, suffering, and the absence of a self.

Samatha Samadhi

Derived from the practice of Samatha meditation, this Samadhi aims for a tranquil and concentrated mind. It's a sort of laser-like focus where the meditator aims to quiet the mind fully.

Zen Samadhi (Zazen)

In Zen traditions, Samadhi is often experienced through the practice of Zazen, or seated meditation. Here, the focus is not just on concentration but also on maintaining an open awareness of the present moment.

Relationship with Earlier Types of Samadhi

In Buddhism, the concept of Samadhi often aligns with the broader goals of wisdom (Prajna) and ethical conduct (Sila). Like the Hindu traditions, the final aim is liberation, albeit defined differently. While certain Buddhist Samadhis like Jhanas may resemble the classical Samprajñata states, the doctrinal framework and ultimate goals differ.

Lesser-Known Types of Samadhi: The Hidden Gems of Meditative Consciousness

While we have delved into the various Samadhi types commonly recognized in classical Yoga and Buddhism, there are lesser-known types of Samadhi that deserve attention. These are often rooted in various mystical and esoteric traditions, both Eastern and Western, and offer a different lens through which to explore consciousness.

The Importance of Lesser-Known Types

The significance of understanding these rare forms of Samadhi is two-fold. First, it adds depth and dimension to the practice for those who may feel that the traditional pathways do not resonate with them entirely. Second, these lesser-known types offer intriguing connections to modern psychology and neuroscience, bridging ancient wisdom with contemporary insights.

Satori: The Zen Flash

While Zen Buddhists often focus on Zazen, another lesser-discussed state is Satori. Often described as a sudden flash of insight or a brief glimpse into one's Buddha-nature, Satori is considered a precursor to more enduring states of enlightenment.

Raja Samadhi: The Royal Union

In certain Tantric traditions, Raja Samadhi is considered the pinnacle of all other forms. Here, the meditator achieves a state of oneness that is said to transcend even the highest levels of Samadhi discussed in classical texts.

Yoga Nidra: Psychic Sleep

Though not always categorized under Samadhi, Yoga Nidra or "psychic sleep" is a state where the practitioner is neither asleep nor fully awake. It’s a form of conscious relaxation that some argue can lead to a Samadhi-like experience.

Sphurana: The Tremor of Stillness

Found in the Kashmir Shaivism tradition, Sphurana is a state of intense stillness, often described as the trembling or throbbing of pure consciousness. It is said to be a gateway into more profound levels of realization.

Cosmic Consciousness

A term popularized in the West, Cosmic Consciousness refers to a state of awareness where the individual feels a sense of unity with the cosmos. While not strictly rooted in Eastern traditions, many consider this a type of Samadhi due to its transformative nature.

Connection to Classical and Buddhist Samadhis

Though these lesser-known types are not explicitly defined in classical Yoga or mainstream Buddhist texts, they can be seen as extensions or variations of the foundational states. For instance, Yoga Nidra’s state of conscious relaxation can be compared to the calm focus in Samatha Samadhi. The instantaneous insight in Satori can be likened to the penetrative understanding in Vipassana Samadhi.

Conclusion: The Spectrum of Samadhi — A Unifying Perspective

Understanding the various types of Samadhi is akin to exploring different facets of a jewel; each aspect reflects a unique shade of light yet contributes to the beauty of the whole.

From the foundational categories outlined in Patanjali's Yoga Sutras to the nuanced types rooted in Bhakti, Tantra, and even modern interpretations, the concept of Samadhi is richly layered.

At the heart of it all is the pursuit of transcendent awareness, a deeper sense of self, and a more profound connection to the universal consciousness.

Whether you resonate more with the cognitive focus found in Samprajñata Samadhi or seek the dissolution of identity in Laya Samadhi, each type serves as a stepping stone toward a deeper, more holistic understanding of existence.

While the types of Samadhi may differ in their approach and theoretical foundations, they all aim towards a singular goal: to uplift the human consciousness to realms of extraordinary clarity and bliss.

And though we may tread various paths, they are united in their ultimate destination.
