उपवासफलात्मकविधिः — Upavāsa as Yajña-Equivalent Merit
Angiras Teaching
यस्तु संवत्सरं पूर्ण चतुर्थ भक्तमश्लुते
yastu saṁvatsaraṁ pūrṇaṁ caturtha-bhaktam aśnute
അംഗിരസൻ പറഞ്ഞു—എന്നാൽ പൂർണ്ണമായൊരു വർഷം (സാധാരണ ആഹാരത്തിന്റെ) നാലിലൊന്ന് മാത്രം ഭക്ഷിക്കുന്നവൻ…
अंगियरा उवाच
The verse points to disciplined moderation in eating as a form of tapas: sustained restraint over time is treated as ethically transformative, generating merit and strengthening self-mastery—key supports for dharma.
Aṅgiras is describing (or beginning to describe) the results of a specific vow: for an entire year the practitioner limits food to a quarter portion, setting up a discussion of the spiritual/ethical fruits of such austerity.
