Matsya Purana — Inquiry into Yayāti’s Story and the Kacha–Devayānī Episode
पुत्रो भूत्वा निष्क्रमस्वोदरान्मे भित्त्वा कुक्षिं जीवय मां च तात अवेक्षेथा धर्मवतीमवेक्षां गुरोः सकाशात्प्राप्य विद्यां सविद्यः //
putro bhūtvā niṣkramasvodarānme bhittvā kukṣiṃ jīvaya māṃ ca tāta avekṣethā dharmavatīmavekṣāṃ guroḥ sakāśātprāpya vidyāṃ savidyaḥ //
Becoming my son, dear one, come forth from my womb—pierce this belly, and restore me to life. And then, having obtained true knowledge from the presence of a teacher, look after (and protect) the righteous woman with due care, as one endowed with learning.
This verse does not describe pralaya or cosmic creation; it focuses on personal dharma—birth, revival, and the obligation to gain knowledge from a guru and protect the righteous.
It emphasizes dharmic responsibility: an heir should be educated under a guru (vidyā) and then use that discernment to protect and care for the virtuous—an ethic applicable to both rulers (protection of subjects) and householders (protection of family and dependents).
No Vastu/temple-building rule appears here; the ritual-cultural emphasis is on guru-based learning and dharma-centered protection rather than architectural procedure.
