Matsya Purana — Paurava Genealogy
प्रवर्तयित्वा तं सर्वम् ऋषिं वाजसनेयकम् विवादे ब्राह्मणैः सार्धम् अभिशप्तो वनं ययौ //
pravartayitvā taṃ sarvam ṛṣiṃ vājasaneyakam vivāde brāhmaṇaiḥ sārdham abhiśapto vanaṃ yayau //
Having thus set the entire affair in motion concerning the sage Vājasaneya, he became embroiled in a dispute with the Brahmins; being cursed, he departed for the forest.
This verse does not address Pralaya; it narrates a social-ethical consequence—dispute with Brahmins leading to a curse and withdrawal to the forest.
It highlights a Dharma theme common in the Matsya Purana: provoking or mishandling conflicts with Brahmins (custodians of ritual and learning) can bring severe consequences, and exile/forest-life appears as a form of enforced or chosen renunciation after moral-social rupture.
No Vāstu or temple-architecture rule is stated here; the only ritual-cultural link is the reference to the Vājasaneyi tradition (Vedic lineage), framed within a dispute involving Brahmins.
