Samkhya
Samkhya is one of the oldest systematic philosophies of India, positing an atheistic dualism between two eternal, uncreated realities: Purusha (consciousness, passive and plural — each soul a distinct witness) and Prakriti (primordial matter, active and unconscious — the single source of all material and mental phenomena). The tradition is attributed to the sage Kapila, though no surviving text bears his name. Ishvarakrishna's 'Samkhya Karika' (c. 4th century CE) is the earliest extant systematic exposition: Prakriti evolves through the interplay of three gunas — sattva (clarity, lightness), rajas (activity, passion), and tamas (inertia, darkness) — producing first the intellect (buddhi), then ego-sense (ahamkara), then mind, senses, and the five material elements. Purusha remains entirely uninvolved in this evolution, a pure witness whose mere proximity catalyzes Prakriti's unfolding. Liberation (kaivalya) comes when Purusha recognizes its absolute distinction from Prakriti and ceases to identify with the products of material evolution.
Worldview
The Samkhya adherent experiences reality as a vast, impersonal theater in which unconscious matter (Prakriti) ceaselessly performs its evolutionary dance while pure consciousness (Purusha) silently witnesses. To hold this ontology is to feel a growing detachment from the drama of the world — not out of indifference, but from the dawning recognition that one's true self is not the body, not the mind, not the emotions, but the unchanging witness behind them all. The interplay of the three gunas (sattva, rajas, tamas) explains every phenomenon from the subtlest thought to the grossest material object. Liberation comes not through action but through discriminative knowledge (viveka) — the clear seeing that consciousness was never entangled in matter, only appeared to be. The mood is one of serene disidentification.
Moral Implications
Samkhya ethics follows from the recognition that suffering arises from the confusion of Purusha with Prakriti — from misidentifying the self with the body, mind, and ego. The moral imperative is discriminative knowledge: to see clearly what is consciousness and what is matter. While Samkhya does not prescribe a detailed ethical code, it implies that actions motivated by ego-identification (ahamkara) perpetuate bondage, while actions performed with detachment and clarity move toward liberation. The ethical life is one of progressive disengagement from the illusions of selfhood, reducing attachment, aversion, and the ignorance that sustains both. Compassion arises naturally when one recognizes that all beings share the same predicament of mistaken identity.
Practical Implications
Samkhya's analytical framework has profoundly shaped Indian medicine (Ayurveda), psychology, and yoga practice. The guna theory provides a practical taxonomy for diet, lifestyle, and mental states — sattvic foods promote clarity, rajasic foods promote agitation, tamasic foods promote lethargy. Yoga (particularly as systematized by Patanjali, who built on Samkhya metaphysics) is the practical discipline through which discriminative knowledge is cultivated. The Samkhya understanding of mind as a material product of Prakriti anticipates aspects of modern cognitive science and encourages a clinical, analytical approach to psychological suffering. Decision-making is guided by the question of whether an action increases sattva (clarity and truth) or deepens tamas (confusion and inertia).
I. Time
Time is emergent from Prakriti's transformations — it does not exist independently but arises as a measure of the gunas' activity. Time is infinite in extent because Prakriti is eternal and its cyclical manifestation and dissolution never cease. It is continuous, cyclical (alternating between cosmic manifestation and dissolution), deterministic (the gunas' interplay follows necessary patterns), and uni-directional within each cosmic cycle.

II. Space
Space is emergent from Prakriti — it is one of the subtle elements (tanmatras) evolved from the primordial matter through the gunas' interplay. Space is infinite, flat, local, and three-dimensional at the macro level. Purusha, being non-material, is inherently non-spatial; it transcends all spatial categories.
Attributes
III. Matter
Matter is substantival and infinite — Prakriti (primordial matter) is eternal, uncreated, and the material cause of everything that exists, from the subtlest mind-stuff to the grossest physical elements. It is conserved: nothing is created or destroyed, only transformed through the gunas' interplay. Matter is local and three-dimensional in its manifest forms. The distinction between Purusha (consciousness) and Prakriti (matter) is the central soteriological insight of Samkhya.
Attributes
IV. Observer
The observer is purusha — pure, unchanging consciousness that witnesses the dance of prakriti (nature) without participating in it. Though associated with a body and mind, purusha is fundamentally disembodied and passive: it does not act, create, or transform — it simply witnesses. Situated in the present moment and bound to a particular psycho-physical complex, the individual purusha's knowledge is mediated and limited by the evolutes of prakriti (mind, ego, senses). Yet through discriminative knowledge (viveka), purusha can recognize its own nature as distinct from prakriti, and this liberating insight is permanently retained. Multiple purushas exist — each an independent center of consciousness — though all share the same fundamental nature as pure, inactive witnesses.
Attributes
V. Energy
Infinite and emergent — energy is a manifestation of Prakriti, arising from the dynamic tension among the three gunas (sattva, rajas, tamas); it has no existence independent of primordial matter. Conservation: Conserved — Prakriti is eternal and indestructible; its total substance is neither created nor destroyed, only transformed through the gunas' interplay. Dispersibility: Reversible — the cycle of cosmic manifestation (srishti) and dissolution (pralaya) is endlessly repeated; all evolved forms return to the unmanifest equilibrium of Prakriti before emanating again.
Attributes
VI. Information
Purusha (consciousness) is the witness of all information; prakriti (nature) encodes information in its evolutes. Information is substantival because both purusha and prakriti are eternal realities. It is conserved because prakriti's transformations preserve information (nothing is lost, only rearranged). It is continuous because prakriti's gunas (qualities) blend continuously.
