Sankhya
Philosophy
Composed by Kapila Muni (c. 3000 BCE), the Sankhya system is the first attempt in human history to enumerate the complete set of principles from which all reality emerges — a Grand Unified Theory in Sanskrit. 25 tattvas from the unmanifest ground state to the gross elements of physical experience.

The Correspondence
Whether this correspondence is coincidence or encoded knowledge remains an open question. The visible (Sattva) universe is ~5% of everything — and that is all we can directly observe. The rest is dark. This is what Sankhya describes.
Purusha — The 25th Tattva
The 24 tattvas above constitute all of physical reality — from quantum fields to the senses. But Sankhya adds a 25th: Purusha, pure witnessing consciousness. It has no physical properties. It cannot be measured. Yet without it, Prakriti never manifests.
In quantum mechanics, the measurement problem asks: what collapses the wave function? The Schrödinger equation describes probabilities. But when we look, one outcome appears. Something outside the equation — the observer — forces a result. Sankhya calls this Purusha. Physics has no name for it yet.
David Chalmers (1995)
Formalized what Vedanta called Purusha as the “hard problem of consciousness”: no amount of physical description explains why there is something it is like to be conscious. The most profound unsolved problem in all of science. Sankhya had the framework 5,000 years earlier.
Historical Context
Kapila Muni's Sankhya Karika (attributed c. 200 CE, but representing a tradition far older) is the oldest systematic philosophical text in any language. Aristotle's Categories (c. 350 BCE) is often cited as the first systematic philosophical analysis — but Sankhya predates it by millennia.
The 24 physical tattvas anticipate the reductionist program of physics — showing that all of experiential reality can be derived from a small set of primitive principles. This is exactly what the Standard Model of particle physics does: 61 fundamental particles explaining all observed matter and forces.
Complete Map of Reality
Purusha
पुरुष
Transcendent
Pure witnessing consciousness. No physical properties — no mass, charge, or spin. The observer that cannot be observed.
Modern Physics
The measurement problem / hard problem of consciousness. The "observer" that collapses the wave function. Has no physical description.
Prakriti
प्रकृति
Manifest Root
The unmanifest primordial nature. The sum of all potentiality before any specific thing arises. The ground state.
Modern Physics
Quantum vacuum / quantum field. The Higgs field / inflaton field. All particles are excitations of Prakriti-like fields.
Mahat / Buddhi
महत् / बुद्धि
Cosmic Mind
Cosmic intelligence — the first emergence from Prakriti. The capacity for discernment. The mathematical structure of reality.
Modern Physics
Laws of physics. The mathematical structure of spacetime. Why does the universe follow mathematical rules? Vedanta: because Mahat IS mathematics.
Ahamkara
अहंकार
Individuation
The principle of individuation — "I-making." Creates the illusion of separate identities from the unified field.
Modern Physics
Symmetry breaking. Decoherence — the quantum-to-classical transition that creates the appearance of separate objects.
Manas
मनस्
Mind
The lower mind — the interface between sensory input and higher intelligence. Processes but does not judge.
Modern Physics
Neural computation / perceptual processing. The limbic and sensory cortex as processors without executive decision-making.
Sattva (Guna)
सत्त्व
Quality of Being
Luminosity, clarity, harmony. The quality of pure, undistorted consciousness-reflection.
Modern Physics
Baryonic matter — the 4.9% of the universe that is visible, luminous, measurable.
Rajas (Guna)
रजस्
Quality of Activity
Activity, motion, expansion, restlessness. The quality of dynamic change.
Modern Physics
Dark energy — the 68.3% driving accelerating expansion of the universe. Pure restless activity.
Tamas (Guna)
तमस्
Quality of Inertia
Inertia, darkness, resistance, density. Obscures the light of consciousness.
Modern Physics
Dark matter — 27.0% of universe. Does not emit, absorb, or reflect light. Pure inertia. The Tamas=Dark Matter ratio: 27%/27% — a remarkable correspondence.
Jnanendriya × 5
ज्ञानेन्द्रिय
Cognitive Sense
Five cognitive faculties: Shrotra (hearing), Tvak (touch), Chakshu (sight), Jihva (taste), Ghrana (smell).
Modern Physics
Sensory nervous system. Each sense maps to a specific sensory cortex region with defined neural pathways.
Karmendriya × 5
कर्मेन्द्रिय
Action Faculty
Five action faculties: Vak (speech), Pani (hands), Pada (feet), Payu (elimination), Upastha (reproduction).
Modern Physics
Motor nervous system. Primary motor cortex controlling limb and vocal movement.
Tanmatra × 5
तन्मात्र
Subtle Element
Five subtle essences: Shabda (sound-essence), Sparsha (touch-essence), Rupa (form-essence), Rasa (taste-essence), Gandha (smell-essence). The qualia before perception.
Modern Physics
Quantum information fields. The "it from bit" proposal (John Wheeler) — information as the substrate of physical reality.
Mahabhuta × 5
महाभूत
Gross Element
Five gross elements: Akasha (space), Vayu (air/force), Tejas (fire/energy), Ap (water/liquid), Prithvi (earth/solid).
Modern Physics
The four fundamental forces + matter: Strong nuclear (Prithvi), Weak nuclear (Vayu), Electromagnetic (Tejas), Gravity (Akasha), Matter substrate (Ap).
