Bhagavad Gītā Chapter 14, Verse 8: Krishna to Arjuna — Guṇatraya-Vibhāga-Yoga

Bhāṣyakāra purports

• Śaṅkaraadvaita

  Tamas (darkness), born of avidya (ignorance) and characterized by moha (delusion), veils the discriminative capacity of every embodied being. Sankara reads this guna as ajna-najam (born of ignorance) in the precise sense that it is not a separate substance but the operative form of the same avidya that conceals Brahman. It binds the jiva through pramada (heedlessness), alasya (inertia), and nidra (sleep) — three expressions of a single failure of viveka (discernment).

• Rāmānujaviśiṣṭādvaita

  Ramanuja distinguishes tamas sharply: where knowledge (jnana) is vastu-yathatmya-avabodha (cognition of things as they truly are), tamas arises from its direct opposite, viparyaya-jnana (inverted cognition), and is therefore mohanam in the sense of producing that very inversion in all embodied souls. It binds indirectly — pramada, alasya, and nidra are its instruments, where pramada is the inattentiveness that diverts one from kartavya-karma (obligatory action) toward Bhagavan, alasya is the stiffness that prevents initiation of action, and nidra the withdrawal of all senses and finally even manas in susupti. The bhakta must recognize tamas not as mere laziness but as cognition structured against Isvara-tattva.

• Madhvadvaita

  For Madhva, tamas is that from which ajnana itself is born — the guna whose very essence is the obscuration that keeps the jiva from recognizing its eternal dependence on Hari. His bhashya is concise and polemical: ajnanam jayate yatas tad ajnanajam — tamas is the source, ignorance is the product, not the reverse. The cross-reference to pramada-mohau tamasah (14.17) is his interpretive anchor: delusion and heedlessness are fruits, not roots. Binding is thus ontological, not merely psychological.

• Vallabhaśuddhādvaita

  Vallabha reads tamas as born either of viruddha-jnana (contradictory cognition) or of avidya — the ambiguity is intentional, holding open the two modes by which Krishna's lila-sakti veils itself. In the Pustimarga understanding, tamas is not an enemy to be destroyed through effort but a withdrawal of Krsna's own prasada (grace); the bound soul is one from whom the sustaining grace has receded. Mohanam is therefore less a cognitive failure than a condition of grace-absence, and the three instruments — pramada, alasya, nidra — describe the texture of a life not yet touched by Krsna's direct nourishment.

• Śrīdharabhakti

  Sridhara Svami grounds the verse in the avarna-sakti (veiling power) of prakrti: tamas rises from the portion of prakrti whose primary characteristic is precisely this power to cover. It is therefore mohanam — generative of bhramti (error, wandering) in all embodied beings. The binding operates through pramada (anavadhanam, inattention), alasya (anudyama, non-initiation of effort), and nidra (citta-avasada, the subsidence or dissolution of the mind). Sridhara's reading is the most textured of the panel in specifying nidra as laya — dissolution — anticipating the later analysis of sleep as tamo-laya in Vedantic epistemology.

• Madhusūdanaadvaita-bhakti

  Madhusudana reads the tu (but) as marking tamas as uniquely distinct from sattva and rajas — not merely a third guna but the one that opposes both: pramada is anti-sattva (it obstructs the clarity that is sattva's work), alasya is anti-rajas (it obstructs the activity that is rajas' work), and nidra is tamo-guna-alambana-vrtti — a mental modification resting entirely on tamas itself, opposed to both. Tamas is ajnanajam from the avarna-sakti-rupa (in the form of the veiling power) of avidya, thus making mohanam not mere confusion but avieka-rupatvena bhramti-janakam (error-generating by being the very form of non-discrimination). This synthesis preserves Sankara's jnana-analysis while opening room for bhakti: the devotee's clarity of Krsna-centered awareness is precisely what tamas extinguishes first.
