16.1 Prakrti (Sâmkhya)

I. Introduction

Historical Background of Samkhya Philosophy

Origin and Development

Samkhya, one of the six orthodox schools of Hindu philosophy, traces its roots to the Rigveda. It was systematically developed by sage Kapila and finds mention in various ancient texts such as the Mahabharata and the Puranas.

Classical Texts

The Samkhya Karika by Ishvarakrishna is a foundational text in this school of thought. Other relevant texts include the Tattvasamasa and the Samkhyasutra.

Philosophical Importance

Samkhya forms the theoretical foundation for the practice of Yoga and is often paired with it. It also influenced other schools like Vedanta and Buddhism.

Core Concepts in Samkhya Philosophy

Dualism of Purusha and Prakrti

The philosophy is fundamentally dualistic, positing two ultimate realities: Purusha (consciousness) and Prakrti (matter).

The Twenty-Four Tattvas

Samkhya enumerates twenty-four tattvas or elements, starting from the most basic, Prakrti, to the most complex, like the mind and senses.

Causality and Evolution

The interaction between Purusha and Prakrti is considered the cause of the universe’s evolution, based on the principle of Satkaryavada, which asserts that the effect is preexistent in its cause. copyright©

What is Prakrti?

Definition and Nature

Prakrti is considered the primal matter, the root cause of the universe in Samkhya philosophy. It is unconscious and inert.

Three Gunas

Prakrti is composed of three gunas: sattva (purity), rajas (activity), and tamas (darkness).

Role in Evolution

Prakrti evolves into various forms, both conscious and unconscious, through its interaction with Purusha.

Significance of Prakrti in Indian Philosophy

In Yoga

In Yoga philosophy, mastering the gunas leads to a balanced mind and spirit, facilitating union with the divine.

In Vedanta

Prakrti is similarly foundational in Vedanta, though it is considered less absolute, subordinated to Brahman, the ultimate reality.

In Ayurveda

Prakrti is vital in Ayurvedic medicine, where it refers to one’s constitution and serves as a basis for individualized treatment.

Comparative Analysis

Samkhya and Buddhism

Though different in their core beliefs, both philosophies share similarities in their analytical approach and acceptance of suffering as an inherent part of life.

Samkhya and Western Philosophy

Samkhya’s dualistic framework bears resemblance to Cartesian dualism, yet diverges in its understanding of consciousness and matter.

II. Historical Overview of Prakrti

The concept of Prakrti is deeply rooted in Indian philosophy.

Origins in Ancient Texts

Rigveda and Samhitas

The Rigveda, one of the oldest Vedic texts, hints at the concept of Prakrti, even though the term is not explicitly used. It is also mentioned in various other Samhitas. copyright©


The Upanishads further develop the idea of Prakrti as the primal substance, intertwined with the concept of Brahman.

Epics and Puranas

In the Mahabharata and Puranas, Prakrti is often personified as a goddess, serving as a complement to the concept of Purusha.

Early Interpretations

In Samkhya

Prakrti was initially articulated in detail within the Samkhya school, describing it as an unconscious, inert primal matter that serves as the basis of all material existence.

Kapila’s Perspective

Sage Kapila, credited with formalizing the Samkhya philosophy, presented Prakrti as the unmanifest material cause of the universe.

Through the Lens of Yoga

The Yoga school adopted and adapted Samkhya’s concept of Prakrti, emphasizing the importance of mastering its three gunas to attain spiritual liberation.

Evolution of the Concept Over Time

Medieval Period

In the medieval period, scholars like Vijnanabhikshu and Gaudapada expanded on the idea of Prakrti by synthesizing it with Vedantic concepts.

Modern Interpretations

In modern times, Prakrti has been viewed through various lenses, including environmentalism, where it is associated with Mother Nature.

Influence on Other Philosophical Schools

In Advaita Vedanta

Prakrti is considered a lower reality, subordinate to Brahman, the ultimate reality, in the Advaita Vedanta school.

In Nyaya and Vaisheshika

These logical and atomistic schools acknowledge Prakrti but place more emphasis on other aspects like logic and categorization. copyright©

In Buddhism and Jainism

Though not part of their core doctrine, both Buddhism and Jainism have been influenced by the idea of Prakrti in certain philosophical discussions.

III. The Basic Nature of Prakrti

The concept of Prakrti in Indian philosophy is both intricate and nuanced.

Defining Characteristics

Inherent Traits

Prakrti is often described as the primordial, undifferentiated substance that forms the basis for material reality.

Unconscious and Inert

Prakrti is devoid of consciousness, acting solely as the substratum for the evolution of the material universe.

Dynamic and Mutable

Despite its inert nature, Prakrti is dynamic, capable of transformation into various forms, both animate and inanimate.

Material vs Immaterial Aspects

Physical Manifestations

Physical entities, from subatomic particles to galaxies, are considered manifestations of Prakrti.

Immaterial Qualities

Prakrti also governs qualities like emotions, thoughts, and desires, though it is fundamentally unconscious.

Relationship with Purusa

Conceptual Dualism

In Samkhya, Prakrti and Purusa are two independent, co-existing realities, integral to the understanding of the cosmos.


Although distinct, Prakrti is influenced by its interaction with Purusa, which leads to the formation and evolution of the universe.

Three Gunas: Sattva, Rajas, Tamas


Sattva represents purity, harmony, and balance. It is the lightest of the three gunas and often associated with divinity. copyright©


Rajas embodies activity, restlessness, and passion. It is the force that drives change and motion in the world.


Tamas signifies darkness, inertia, and ignorance. It is the heaviest of the gunas, often responsible for stagnation and deterioration.

Role in the Formation of the Universe

Cosmological Significance

In Samkhya, Prakrti is considered the material cause of the universe, responsible for its formation and its diverse manifestations.

Principle of Satkaryavada

According to the principle of Satkaryavada, the effect (universe) preexists in its cause (Prakrti), setting the stage for cosmic evolution.

IV. Prakrti in Classical Texts

Prakrti plays a crucial role in Indian classical texts

References in the Upanishads

Conceptual Foundations

The Upanishads serve as an essential framework for Prakrti, linking it with the idea of Brahman and the ultimate reality.

Philosophical Inquiry

Prakrti is often discussed in the context of metaphysical questions about the nature of reality, existence, and consciousness.

Explanation in the Bhagavad Gita

Krishna’s Discourse

In the Bhagavad Gita, Lord Krishna elaborates on Prakrti as the material cause of the universe and its relationship with Purusa.

Ethical and Spiritual Dimensions

Discussion in Sâmkhya Karika

Ishvarakrishna’s Contributions

Sâmkhya Karika, attributed to Ishvarakrishna, serves as a pivotal text for the Samkhya philosophy, providing detailed definitions and explanations of Prakrti. copyright©

The Twenty-Four Tattvas

Prakrti plays a significant role in various cosmological theories in Indian philosophy

Satkaryavada Principle

This principle posits that the effect pre-exists in the cause, and in this case, the universe pre-exists in Prakrti.

Asatkaryavada Opposition

Some schools of philosophy oppose Satkaryavada, arguing that the effect does not pre-exist in the cause.

Mahat and Ahamkara

Mahat: The Cosmic Mind

Mahat, the first product of the evolution of Prakrti, represents cosmic intelligence and is often equated with Buddhi.

Ahamkara: The Cosmic Ego

Ahamkara evolves from Mahat and is responsible for the notion of individuality in living beings.

Creation and Dissolution of the Universe

Process of Manifestation

Prakrti undergoes a process of transformation to create the material world, following the principle of Satkaryavada.

Cycle of Dissolution

The material universe eventually dissolves back into its primordial state, merging back into Prakrti. copyright©
