Matsya Purana — The Tale of Brahmadatta: Past-life Memory
अहमेवाद्य हसिता न जीविष्ये त्वयाधुना कथं पिपीलिकालापं मर्त्यो वेत्ति विना सुरान् //
ahamevādya hasitā na jīviṣye tvayādhunā kathaṃ pipīlikālāpaṃ martyo vetti vinā surān //
“I alone have been laughed at today; now I will not live because of you. How could a mortal understand even the speech of ants, without the gods?”
It underscores that during extraordinary cosmic events like Pralaya, human understanding is inadequate without divine guidance—hinting at the dependence on the gods (and, in the broader episode, on Lord Matsya’s instruction).
It teaches humility and restraint in judgment: a ruler or householder should recognize the limits of personal knowledge and seek counsel from dharmic authorities (sages, scripture, and the divine) before acting.
No direct Vastu or temple-building rule appears here; the ritual takeaway is the broader principle that correct practice depends on revealed or divinely guided knowledge, not mere human inference.
