Matsya Purana — The Greatness of the Vibhūti-Dvādaśī Vow: Pushkara
मुनिरभ्यधादथ भवान्तरितं समीक्ष्य पृथ्वीपतेः प्रसभमद्भुतहेतुवृत्तम् जन्माभवत्तव तु लुब्धकुले ऽतिघोरे जातस्त्वमप्यनुदिनं किल पापकारी //
munirabhyadhādatha bhavāntaritaṃ samīkṣya pṛthvīpateḥ prasabhamadbhutahetuvṛttam janmābhavattava tu lubdhakule 'tighore jātastvamapyanudinaṃ kila pāpakārī //
Then the sage spoke: “Having examined your intervening (past) existence, I have seen the forceful course of events—arising from a wondrous cause—connected with the king of the earth. Because of that, your birth occurred in a most terrible hunter clan; and you too, indeed, have been committing sinful deeds day after day.”
This verse is not about Pralaya; it teaches karmaphala—how past lives and actions determine one’s present birth and suffering.
It warns rulers and householders that unethical conduct has consequences across lifetimes; sustained daily wrongdoing can lead to degradation of status and painful rebirth, so dharma and restraint are essential.
No Vastu/temple-building or ritual procedure is mentioned; the focus is moral causality (karma), rebirth, and the identification of sin as a daily habit to be corrected.
