Matsya Purana — Agastya’s Origin
होमं कृत्वा ततः पश्चाद् वर्जयेन्मानवः फलम् अनेन विधिना यस्तु पुमानर्घ्यं निवेदयेत् //
homaṃ kṛtvā tataḥ paścād varjayenmānavaḥ phalam anena vidhinā yastu pumānarghyaṃ nivedayet //
Having performed the fire-offering (homa), thereafter a man should refrain from seeking the fruit (of the rite). But whoever offers arghya according to this prescribed method—
This verse is not about Pralaya; it teaches ritual discipline—performing homa and offering arghya without attachment to the expected “fruit” of the rite.
It frames a core dharmic ethic for householders (and rulers acting as ritual patrons): complete prescribed worship (homa, arghya) while avoiding selfish expectation of reward—an ideal of niṣkāma (non-attached) performance.
The ritual takeaway is procedural: homa is performed first, and arghya is to be offered according to a fixed vidhi; the verse also stresses that rites should be done without craving their results.
