Bhagavad Gītā Chapter 17, Verse 28: Krishna to Arjuna — Śraddhātraya-Vibhāga-Yoga
Whatever sacrifice, gift, or austerity is performed without faith is called "unreal," Arjuna. It bears no fruit in this world or the next.
Bhāṣyakāra purports
- Śaṅkaraadvaita
Whatever oblation (huta), gift (datta), austerity (tapas), or act of reverence such as praise and prostration (stuti-namaskara-adi) is performed without shraddha is called asat — it falls outside the path leading to the attainment of the Self (mat-prapti-sadhana-marga-bahya). Shankara is explicit: however great the effort expended, such action bears no fruit hereafter (pretya) and no result here (iha), because the wise censure it (sadhu-nindita). The verse seals Chapter 17 by making shraddha the epistemological gate: without the inner alignment that recognises action as means to liberation, the act has no ontological weight.
divergence: Shankaracharya on 17.28 — mat-prapti-sadhana-marga-bahyatvat pArtha, sadhu-ninditat iha na phalatvam
- Rāmānujaviśiṣṭādvaita
Even scripturally prescribed acts — homa, dana, tapas — when performed without shraddha are asat. Ramanuja's reasoning is stark and two-directional: they yield neither moksha (na pretya) nor worldly fruit (no iha). For Ramanuja shraddha is not merely psychological sincerity but the devotional orientation toward Bhagavan as the sole enjoyer and end of all action; without that orientation the act is ontologically hollow — it fails both registers of result simultaneously. Kainkarya without the servant's love is no kainkarya at all.
divergence: Ramanuja on 17.28 — na moksaya na samsarikaya ca phalaya iti
- Madhvadvaita
Madhva grounds the verdict in Vedic testimony, citing the Rigveda-khilas: only that karma which is performed for Brahman (tad-artham) is truly sat; karma divorced from Brahman-priti is nishphala — fruitless. The permanent ontological distinction between jiva and Ishvara means no act has intrinsic merit; merit is conferred entirely by Brahman's proximity (tac-chabdanam sannidher) and the agent's orientation toward Him. Without shraddha directed at Hari, even elaborate yajna is merely mechanical motion — it does not generate the apurva that binds to Bhagavan.
divergence: Madhva citing Rigveda-khilas — yajna-adya nishphalam karma tat syat sad vai tad-arthakam
- Vallabhaśuddhādvaita
For Vallabha the word is swift and without ornament: yajna, huta, and dana performed without shraddha toward Krishna are asat — empty, purposeless (vyartha). The two-world formula (ubhaya-loka-sukha-asadhakatva) is the measure: Pushti-marga holds that Krsna's prasada alone makes any act real; shraddha here is the openness to receive His lila-prasada. Any act sealed off from that reception — however ritually correct — fails both worlds because it is not woven into Krishna's play.
divergence: Vallabha on 17.28 — shraddha-rahitya = asat = ubhaya-loka-sukha-asadhakatva
- Śrīdharabhakti
Sridhara opens with an explicit purpose statement absent in most other bhashyas: the verse is here to motivate shraddha-purva-pravritti in all karma (idanim sarva-karmasu shraddhayaiva pravritti-artham). Huta, datta, tapta-tapas, and any other act (yanyan-yad api krtam karma) performed without shraddha are asat. The dual failure is carefully distinguished: in the other world (pretya) it fails because it is vigunam — deficient in quality, incapable of generating the apurva that matures into fruit; in this world (iha) it fails because it is ayasha-skara — it brings disgrace. Shraddha is thus not optional adornment but the condition of both ritual efficacy and social honour.
divergence: Sridhara on 17.28 — viguna-tvat pretya na phalati; ayasha-skara-tvat iha na phalati
- Madhusūdanaadvaita-bhakti
Madhusudana delivers the most architecturally elaborate reading. He has just explained (17.26-27) that the OM-TAT-SAT formula can repair accidental deficiency (vaigunaya) in shraddha-purva sattvik yajna; now he closes the loop: for those who act without shraddha at all — driven by kama-kara, having abandoned shastriya-vidhi (asura-sadharma) — no OM-TAT-SAT invocation can supply what is categorically absent. Like attempting to sprout a seed from stone (shilaya iva ankurasya), the asat act is wholly unfit (sarva-tha tad-ayogyatva). It bears no fruit hereafter (apurva-ajanakam) and earns no esteem here (sadhu-nindita). The synthesis-point: the OM-TAT-SAT remedy presupposes shraddha; shraddha is the indispensable substrate on which all three divine names operate. Without it, even bhakti's corrective apparatus is inoperative.
divergence: Madhusudana on 17.28 — shilaya iva ankuras tat-kasmat asat; om-tat-sat nirdeshena na tasya sadhu-bhavah shakyate kartum
