Samkhya
What it is
Samkhya is the oldest of the six classical schools of Indian philosophy, and it is the map of the inner architecture that most of this wiki is standing on. It holds that everything which exists resolves into two eternal and distinct realities. Purusha is consciousness: unchanging, without attributes, doing nothing, only witnessing. Prakriti is nature: everything that has form, movement, mind, matter or quality, including the parts of a person that most people would call themselves.1
The single most consequential claim in the system is that the mind belongs to Prakriti. Thought, intellect, ego, memory and emotion are all material in this account. They are fine and subtle material, but they are on the nature side of the line, and consciousness is the thing watching them. Every practice in this tradition that asks a person to observe their own mind rather than identify with it is operating on this claim.
Samkhya is also the reason this work speaks about a person in the vocabulary it uses. Buddhi, Manas, Ahamkara, the three gunas and the elements are Samkhya categories. The Health Balance Score Card describes itself as drawn from Samkhya, the oldest map of your inner architecture, and this is the page that claim rests on.
Sanskrit and etymology
Sāṃkhya (सांख्य) comes from sam (together, complete) and khyā (to reckon, to name, to count). The usual translations are “enumeration” or “reckoning”.
The name describes the method rather than a doctrine. Samkhya works by counting. It takes the whole of experience and resolves it into a fixed, ordered list of principles, and the philosophical work is done by getting the list and the order right. A system named “enumeration” is telling you in advance that its central act is discrimination: separating what had been experienced as one undifferentiated thing into its actual constituents, and then seeing which of them you are.
Tattva (तत्त्व), the word for each item on the list, is literally “that-ness”, the principle of a thing.
The twenty-five tattvas
The classical enumeration runs to twenty-five.2
| Tattva | What it is | |
|---|---|---|
| 1 | Purusha | Consciousness. Witness. Without qualities, inactive, plural in classical Samkhya. |
| 2 | Prakriti | Unmanifest nature, holding the three gunas in equilibrium. |
| 3 | Mahat or Buddhi | The first evolute. Intellect, the faculty that discriminates and decides. |
| 4 | Ahamkara | The I-maker. The function that appropriates experience and calls it mine. |
| 5 | Manas | The sensory mind, which processes and coordinates what the senses bring. |
| 6–10 | Jnanendriyas | Five faculties of knowing: hearing, touch, sight, taste, smell. |
| 11–15 | Karmendriyas | Five faculties of action: speech, grasping, locomotion, elimination, generation. |
| 16–20 | Tanmatras | Five subtle essences: sound, touch, form, taste, odour. |
| 21–25 | Panch Mahabhutas | Five gross elements: space, air, fire, water, earth. |
The order carries the argument. Intellect appears before ego, and ego appears before the sensory mind. A person is therefore not built up from the senses inward. They are built from discrimination outward, and the sense of being a separate self shows up in the middle of that sequence rather than at the bottom of it.
The three gunas
Prakriti is constituted of three strands, and everything made of Prakriti carries all three in some proportion. Sattva is clarity, lightness and balance. Rajas is movement, drive and agitation. Tamas is inertia, heaviness and obscuration. They are not good, neutral and bad. They are three modes, and every state of body and mind is a ratio between them at a moment.
This is the machinery behind a great deal of what the practice actually does. Fasting, diet, the timing of sleep, the company a person keeps and the content they consume are all treated in this tradition as inputs to that ratio. The wiki has separate pages for each of the three; this page is their parent.
Where it appears in the canon
Kapila is named as the founder throughout the tradition. He is a figure of the literature rather than a historically documented person, and the Samkhya Sutras attributed to him are a late compilation, generally placed around the fourteenth century CE, far after the classical system was already complete.
The Samkhya Karika of Ishvarakrishna is the earliest surviving systematic text of the school, seventy-two verses in the arya metre, compressing the entire system into a form short enough to memorise. Scholars date it broadly between the third and fifth centuries CE, with many favouring around 350 CE.3 Everything on this page that is described as classical Samkhya comes from that text.
Samkhya ideas run much earlier than the Karika, appearing in the Katha and Shvetashvatara Upanishads and through the Mahabharata. The second chapter of the Bhagavad Gita is called Samkhya Yoga, and the Gita’s account of the gunas in chapters fourteen and seventeen is Samkhya vocabulary put to devotional use.
Patanjali’s Yoga Sutras take the Samkhya metaphysics almost entire and add one thing, Ishvara. This is the relationship most worth holding: Samkhya supplies the map, Yoga supplies the method for walking it. Classical Samkhya is nirishvara, without a lord, and works by discriminative knowledge alone. Yoga is seshvara, and works by practice. The pairing of the two as a single tradition is ancient and deliberate.
In the Bihar School of Yoga curriculum, Samkhya is taught as the theoretical ground beneath the practices rather than as a separate subject, which is why a practitioner can absorb its categories for years through terms like guna and buddhi without ever meeting the word Samkhya itself.
What is contested
The dating is genuinely open. A two-century spread on the Karika is not a rounding error, and everything before it is reconstructed from fragments and from what later commentators say the earlier teachers held.
Whether classical Samkhya is atheistic is disputed. It is commonly described that way because it does not require a creator god to explain the universe. Several scholars argue this overstates a technical absence into a theological position. The tradition itself has rarely treated the question as important.
Plurality of Purusha is a real difficulty. Classical Samkhya holds that there are many Purushas, one per being. This sits awkwardly beside the Advaita Vedanta position of a single consciousness, which Adi Shankaracharya argued for directly against Samkhya. This wiki draws on both traditions, and the tension is not resolved here.
“Evolution” is a poor translation. Parinama, the process by which Prakriti unfolds into the tattvas, is the changing of a substance that was already there, closer to milk becoming curd than to Darwinian descent. Samkhya writing in English routinely borrows the biological word and imports an implication the Sanskrit does not carry.
This wiki mixes two systems. Pancha Kosha, the five sheaths, is Vedantic and comes from the Taittiriya Upanishad. Buddhi, Ahamkara, Manas and the gunas are Samkhya. Both frames appear across these pages, sometimes on the same page. They are compatible in practice and distinct in origin, and a reader should know which one they are standing in.
Why it matters
It is the reason the assessment looks at a person in layers. If the mind is material, then a state of mind is something with constituents that can be named, and a reading of a person becomes possible in principle. The HBSC is an attempt at exactly that, and it inherits both its ambition and its vocabulary from this system.
It explains the mechanism behind the Shadripus. The six inner enemies are described on that page as arising when Buddhi is overwhelmed by Manas and conditioned impressions take the wheel. That sentence is unintelligible outside Samkhya and precise inside it. It names a specific inversion in a specific ordered hierarchy.
It sets the limit on self-improvement. A system where the watcher is already complete and unchanging cannot promise to improve the watcher. What it offers is the separation of the watcher from what it had been identifying with. This is the philosophical root of the “A Little” position: no dramatic promises are available here, because on this account there is nothing wrong with the one who is looking.
It is what makes the food and the breath work theoretically continuous. If a meal, a breath and a thought are all made of the same three strands in different proportions, then the Annamaya Index and Pranayama and the evening review are three instruments operating on one substance. Without Samkhya they are three unrelated wellness activities that happen to be sold together.

Notes
Future work could pursue: a page for each of the three unwritten spine terms this page leans on, Guna, Ahamkara and Panch Mahabhutas, which between them carry a large share of the wiki’s remaining unresolved links; the tanmatra to mahabhuta sequence read against what is currently known about sensory processing, which is the most testable-looking claim in the system and the one most often overstated; a careful treatment of the Samkhya and Vedanta tension named above, since the wiki currently uses both frames without saying so; and the question of whether the gunas can be operationalised at all, which is the load-bearing question under the HBSC and deserves its own page rather than an assumption.
Terms used on this page that do not yet have pages of their own: Panch Mahabhutas, Patanjali, Yoga Sutras. They are left unlinked deliberately, because the published folders render an unresolved link as a live 404.
