Matsya Purana — The Tale of Brahmadatta: Past-life Memory
सर्वसत्त्वरुतज्ञं मे देहि योगिनमात्मजम् एवमस्त्विति विश्वात्मा तमाह परमेश्वरः //
sarvasattvarutajñaṃ me dehi yoginamātmajam evamastviti viśvātmā tamāha parameśvaraḥ //
“Grant me a son who is a yogin and who understands the cries and speech of all beings.” Thus addressed, the Supreme Lord—the Soul of the universe—replied, “So be it.”
This verse does not describe Pralaya directly; it highlights divine governance through boons—showing the Supreme Lord’s role as Viśvātmā who sanctions outcomes in the cosmic order that later frames Manvantara and Pralaya narratives.
It reflects the ideal of seeking progeny endowed with spiritual discipline and compassion—implying that rulers/householders should desire heirs who are self-controlled (yogin) and sensitive to all beings, supporting dharmic governance and non-harm.
No Vāstu or temple-building rule is stated; the ritual takeaway is the efficacy of petitioning the Supreme Lord for a boon and the doctrinal emphasis on yoga as a valued qualification.
