Matsya Purana — The Madana-Dvādaśī Vow and the Birth of the Maruts
विधास्यामि ततो गर्भम् इन्द्रशत्रुनिषूदनम् आपस्तम्बस्ततश्चक्रे पुत्रेष्टिं द्रविणाधिकाम् //
vidhāsyāmi tato garbham indraśatruniṣūdanam āpastambastataścakre putreṣṭiṃ draviṇādhikām //
“Then I shall bring about a conception—one who will become the slayer of Indra’s enemy.” Thereupon Āpastamba performed the Putreṣṭi sacrifice, rich in wealth and offerings.
This verse does not discuss Pralaya; it focuses on the deliberate ritual causation of conception through a Putreṣṭi sacrifice, highlighting karmic-ritual generation rather than cosmic dissolution.
It reflects the dharmic ideal that progeny (especially an heir) may be sought through sanctioned śrauta rites performed by qualified priests, with proper dakṣiṇā (wealth/gifts), aligning royal/householder aims with Vedic ritual duty.
The significance is ritual: Putreṣṭi is explicitly named as a son-producing sacrifice, described as draviṇādhikā—implying full provision of offerings and priestly fees, a key requirement for efficacy in śrauta procedure.
