1.4 Brief Introduction to Samkhya and Yoga Darshana

Brief Introduction to Samkhya and Yoga Darshana

Quick Answer: Syllabus Topic 1.3 examines the sister orthodox philosophical systems (Samana-Tantra) of Samkhya Darshana (founded by Maharshi Kapila, 25 Tattvas, Nir-Ishvara) and Yoga Darshana (codified by Maharshi Patanjali, 26 Tattvas including Ishvara, Se-Ishvara). Samkhya provides the theoretical metaphysics—dualism of conscious Purusha and three-Guna Prakriti evolving via Satkaryavada—while Yoga provides the practical psychological discipline (Ashtanga Yoga) to still the Chitta Vrittis and realize Kaivalya.

Taxonomy of Indian Philosophy: Astika vs. Nastika Darshanas

In Sanskrit, philosophy is called Darshana, derived from the root Drish (दृश् — "to see" or "direct vision of truth"): "Drishyate anena iti darshanam" (that through which reality is directly realized). Indian philosophical traditions are divided into two groups based on whether they accept the epistemological authority (Pramanya) of the Vedas (NOT whether they believe in a personal creator God):

1. Six Astika (Orthodox / Vedic) Darshanas (Shad-Darshanas): Accept the authority of the Vedas, organized into three allied pairs (Samana-Tantra):
   • Nyaya (Maharshi Gautama / Akshapada — Nyaya Sutras: logic and 4 Pramanas) & Vaisheshika (Maharshi Kanada / Uluka — Vaisheshika Sutras: atomic theory/Paramanuvada and 6–7 Padarthas).
   • Samkhya (Maharshi Kapila — Samkhya Pravachana Sutra & Ishvarakrishna's Samkhya Karika) & Yoga (Maharshi Patanjali — Yoga Sutras).
   • Purva Mimamsa (Maharshi Jaimini — Mimamsa Sutras: ritual dharma and Karma-Kanda) & Uttara Mimamsa / Vedanta (Maharshi Badarayana / Vyasa — Brahma Sutras: inquiry into Brahman).
2. Three Nastika (Heterodox / Non-Vedic) Darshanas: Reject the infallibility of the Vedas:
   • Charvaka / Lokayata (Brihaspati): Materialism accepting only direct perception (Pratyaksha) and four elements (excluding Akasha).
   • Jaina Darshana (Rishabhadeva to Lord Mahavira): Pluralistic realism (Anekantavada, Syadvada, Jiva vs. Ajiva).
   • Bauddha Darshana (Gautama Buddha): Four Noble Truths (Chatur-Arya-Satya), Dependent Origination (Pratityasamutpada), and Momentariness (Kshanikavada).

Metaphysics of Samkhya Darshana

Founded by Maharshi Kapila (who taught his disciple Asuri, who taught Panchashikha) and preserved in its earliest extant authoritative text, Ishvarakrishna's Samkhya Karika (72 verses in Arya meter), the word Samkhya means both "number / enumeration" (enumerating the 25 ultimate principles or Tattvas) and "right discriminative knowledge" (Samyak Khyati / Viveka-Jnana).

1. Radical Dualism (Dvaita): Purusha and Prakriti

Samkhya posits two ultimate, eternal, uncreated, and mutually independent realities:

2. Theory of Causation: Satkaryavada (Prakriti-Parinamavada)

Samkhya upholds Satkaryavada (Sat = existent + Karya = effect + Vada = doctrine): the effect pre-exists latently in its material cause prior to its production (Samkhya Karika 9)—just as sesame oil already exists in sesame seeds, or curd in milk. Nothing can be produced out of nothing (Asat-akarana). Specifically, Samkhya advocates Prakriti-Parinamavada: the world is a real transformation (Parinama) of Prakriti (unlike Advaita Vedanta's Vivartavada, which views the world as an apparent superimposition on Brahman).

3. The Three Gunas (Trigunas) & Cosmic Evolution (Sarga)

Prakriti is the state of equilibrium (Samyavastha) of three constituent forces or strands called Gunas:

• Sattva Guna: Principle of buoyancy, illumination, clarity, harmony, and pleasure (Sukha). Symbolized by the color white.
• Rajas Guna: Principle of activity, motion, passion, stimulation, and pain/restlessness (Duhkha). Symbolized by the color red.
• Tamas Guna: Principle of inertia, heaviness, restraint, obscuration, and delusion/apathy (Moha). Symbolized by the color black/dark.

How Evolution Begins (Pangvandha-Nyaya): By itself, Purusha is conscious but inactive (like a lame man with good eyesight), while Prakriti is active but unconscious/blind (like a blind man who can walk). Through the mere proximity (Sannidhi) of Purusha—like a magnet moving iron filings—the equilibrium of the three Gunas in Prakriti is disturbed (Guna-kshobha). They cooperate for a dual purpose (Samkhya Karika 21): providing worldly experience (Bhoga) to Purusha and ultimately bringing about liberation (Apavarga / Kaivalya).

The 25 Tattvas of Samkhya & the Fourfold Causal Classification

In Samkhya Karika 3 ("Mula-prakritir avikritir mahadadyah prakriti-vikritayah sapta, shodashakas tu vikaro na prakritir na vikritih purushah"), all 25 Tattvas are classified into four causal groups:

1. Neither Cause nor Effect (Na Prakritir Na Vikritih) — 1 Tattva:
   • (1) Purusha (Pure Consciousness).
2. Root Cause Only, Never an Effect (Mula-Prakritir Avikritih) — 1 Tattva:
   • (2) Mulaprakriti / Avyakta (Unmanifest Primordial Nature).
3. Both Cause and Effect (Prakriti-Vikritayah) — 7 Tattvas:
   • (3) Mahat or Buddhi (Cosmic / Individual Intellect — first evolute of Prakriti).
   • (4) Ahamkara (Ego-principle — evolves from Mahat and branches into three modes: Vaikarika/Sattvika, Taijasa/Rajasika, and Bhutadi/Tamasika).
   • (5–9) Five Tanmatras (Subtle Elements evolving from Tamasika/Bhutadi Ahamkara assisted by Rajas): Shabda (sound), Sparsha (touch), Rupa (form/color), Rasa (taste), and Gandha (smell).
4. Effects Only, Never a Material Cause of Another Tattva (Shodashakas Tu Vikarah) — 16 Tattvas:
   • (10) Manas (Mind — central coordinating organ of both perception and action, called Ubhayendriya, evolving from Sattvika Ahamkara).
   • (11–15) Five Jnanendriyas / Buddhindriyas (Organs of Sensory Perception, from Sattvika Ahamkara): Shrotra (ears), Tvak (skin), Chakshu (eyes), Rasana (tongue), and Ghrana (nose).
   • (16–20) Five Karmendriyas (Organs of Action, from Sattvika Ahamkara energized by Rajas): Vak (vocal cords/speech), Pani (hands/grasping), Pada (feet/locomotion), Payu (excretory organ), and Upastha (reproductive organ).
   • (21–25) Five Panchamahabhutas (Gross Elements evolving from the 5 Tanmatras): Akasha (ether/space from Shabda), Vayu (air from Shabda + Sparsha), Agni/Tejas (fire from Shabda + Sparsha + Rupa), Ap/Jala (water from Shabda + Sparsha + Rupa + Rasa), and Prithvi (earth from all five Tanmatras).

Comparison of Samkhya Darshana and Yoga Darshana

While Samkhya and Yoga share the same epistemology (three Pramanas: Pratyaksha [direct perception], Anumana [inference], and Agama / Aptavachana [authoritative scriptural testimony]), they differ on two major points tested on the exam:

In Patanjala Yoga Sutra 1.24 ("Klesha-karma-vipakashayair aparamrishtah purusha-vishesha Ishvarah"), Patanjali defines the 26th Tattva, Ishvara, as a special Purusha (Purusha-vishesha) who is eternally untouched by the five afflictions (Kleshas), actions (Karma), their fruits (Vipaka), and latent impressions (Ashaya), and who serves as the unconditioned Guru of even the earliest ancient sages (Purvesham api guruh kalenanavachchhedat — PYS 1.26), signified by the mystic syllable Pranava (Om) (PYS 1.27).
