Introduction
If you're studying Yoga philosophy, understanding Samkhya Darshana is essential. Why? Because the entire metaphysical framework of Patanjali’s Yoga Sutras is deeply rooted in Samkhya. In fact, Yoga Darshana is often called “Applied Samkhya.”
In this blog, we’ll explore Samkhya Darshana in detail - its origin, key texts, the Purusha - Prakriti duality, its theory of creation, epistemology, and how it connects with Yoga. Let’s begin with what Samkhya actually means.
What is Samkhya Darshana?
The term "Samkhya" comes from the Sanskrit root sam + khya, meaning enumeration or number. Philosophically, it refers to a system that "counts out" the tattvas - the fundamental principles that make up reality.
It’s one of the six classical Astika Darshanas (orthodox schools) of Hindu philosophy. Sankhya offers a rational, analytical approach to liberation, outlining 25 tattvas (principles) and detailing how misidentification with matter leads to bondage.
Kapila Muni and the Samkhya Sutras
Kapila Muni is the legendary sage who founded Samkhya Darshana. He’s believed to have composed the Samkhya Sutras, a foundational yet now mostly lost collection of aphorisms that systematized this philosophy.
Though the original Sutras aren't available in full, Kapila's teachings are preserved in later texts and are frequently referenced in the Mahabharata, Bhagavad Gita, and Puranas.
Ishvara Krishna's Sankhya Karika: The Core Text
The most authoritative surviving text of Sankhya is Samkhya Karika, composed by Ishvara Krishna (~4th century CE). In just 72 verses, this text beautifully summarizes the entire Samkhya system:
The 25 tattvas (principles of existence)
The Purusha - Prakriti duality
The theory of Satkarya Vada
The purpose of liberation (Kaivalya)
This text became the standard manual of Samkhya, widely studied and commented upon by Indian scholars for centuries.
Purusha and Prakriti: The Core Dualism
At the heart of Smnkhya is the metaphysical dualism between:
Purusha – the eternal, unchanging, conscious Self (pure awareness).
Prakriti – the unconscious, ever-changing Nature, comprising all mind and matter.
Purusha is the witness, never doing anything.Prakriti is the doer, creating the entire cosmos through evolution.
All of life’s drama unfolds because Purusha misidentifies with the evolutes of Prakriti. Liberation happens when one realizes:“I am not the body, mind, or ego - I am pure consciousness.”
Satkarya Vada: Theory of Causation
Samkhya upholds the principle of Satkarya Vada - the effect pre-exists in the cause. Nothing arises from nothing. For example:
A clay pot was already present in clay.
The universe was already present in Prakriti, in an unmanifest state.
Thus, creation is evolution, not invention. All manifest things were latent in Prakriti and evolved when the balance of the three gunas (qualities) was disturbed.
The 25 Tattvas: How Prakriti Evolves
According to Samkhya, Prakriti evolves into 23 tattvas, which, along with Prakriti and Purusha, make up the 25 tattvas:
Prakriti (Primordial Nature)
Mahat / Buddhi (Intellect)
Ahamkara (Ego)
Manas (Mind)5–9. Five Jnanendriyas (Sensory Faculties)10–14. Five Karmendriyas (Motor Faculties)15–19. Five Tanmatras (Subtle Elements)20–24. Five Mahabhutas (Gross Elements)
Purusha (Consciousness)
This model explains not just the cosmos, but also our internal psychology -mind, ego, senses, body - all are evolutes of Prakriti.
The Three Gunas: Sattva, Rajas, Tamas
Everything in Prakriti is made of three gunas:
Sattva – purity, clarity, wisdom
Rajas – activity, passion, motion
Tamas – inertia, darkness, delusion
The interplay of these gunas causes creation, sustenance, and dissolution. In the path of Yoga, we aim to increase Sattva, discipline Rajas, and reduce Tamas to prepare the mind for liberation.
Samkhya Epistemology: How We Know What We Know
Samkhya recognizes three valid sources of knowledge (pramanas):
Pratyaksha – Direct Perception
Anumana – Inference
Shabda (Apta Vakya) – Scriptural or reliable testimony
These pramanas allow us to discriminate between Purusha and Prakriti, leading to viveka khyati (discriminative wisdom) and ultimately, kaivalya (liberation).
Core Concepts: Kaivalya, Karma, Rebirth, and Mind
Kaivalya – Isolation of Purusha from Prakriti, the goal of Samkhya.
Karma – Actions in Prakriti cause samsara (cycle of birth and death).
Rebirth – Due to ignorance, the subtle body (mind, ego) transmigrates.
Mind (Antahkarana) – Composed of Buddhi, Ahamkara, and Manas - entirely material, not conscious.
Samkhya teaches that Purusha is never bound, but appears so due to identification with the evolutes of Prakriti.
Samkhya and Yoga: Two Wings of the Same Bird
Patanjali’s Yoga Darshana adopts the entire metaphysics of Samkhya but introduces Ishvara (a special Purusha) as an optional object of devotion.
Sankhya | Yoga |
Focuses on Jñana (knowledge) | Focuses on Abhyasa (practice) |
No concept of Ishvara | Accepts Ishvara as a helpful guide |
Goal: Kaivalya | Goal: Kaivalya |
Liberation through Viveka | Liberation through Viveka aided by practice |
Thus, Samkhya is the philosophy, and Yoga is the practical methodology to realize that philosophy.
