Matsya Purana — Inquiry into Yayāti’s Story and the Kacha–Devayānī Episode
*शौनक उवाच गुरोः सकाशात्समवाप्य विद्यां भित्त्वा कुक्षिं निर्विचक्राम विप्रः प्रालेयाद्रेः शुक्लमुद्भिद्य शृङ्गं रात्र्यागमे पौर्णमास्यामिवेन्दुः //
*śaunaka uvāca guroḥ sakāśātsamavāpya vidyāṃ bhittvā kukṣiṃ nirvicakrāma vipraḥ prāleyādreḥ śuklamudbhidya śṛṅgaṃ rātryāgame paurṇamāsyāmivenduḥ //
Śaunaka said: Having obtained sacred knowledge in the presence of his guru, the brāhmaṇa burst forth, splitting the womb, appearing like the full moon on the night of the full-moon day, breaking out in shining whiteness from the snowy mountain’s peak.
This verse does not describe Pralaya; it uses cosmological imagery (the full moon emerging) to poetically depict a miraculous emergence/birth connected to receiving knowledge from a guru.
Indirectly, it elevates vidyā gained through the guru as transformative—supporting the Purāṇic ethic that rulers and householders should honor teachers, pursue disciplined learning, and uphold brahminical counsel in dharma.
No Vāstu or temple-building rule appears here; the key takeaway is ritual-cultural: the guru’s proximity and transmission of knowledge are portrayed as potent enough to ‘bring forth’ a new state of being.
