Matsya Purana — Yadu Lineage
देवक्यां वसुदेवस्य तपसा पुष्करेक्षणः चतुर्बाहुस्तदा जातो दिव्यरूपो ज्वलञ्श्रिया //
devakyāṃ vasudevasya tapasā puṣkarekṣaṇaḥ caturbāhustadā jāto divyarūpo jvalañśriyā //
By the austerity of Vasudeva, the lotus-eyed Lord was then born in Devakī—four-armed, of divine form, blazing with splendor.
This verse is not about Pralaya; it emphasizes divine manifestation (avatāra) through tapas, showing how cosmic divinity becomes present in history for protection and dharma.
It highlights tapas (disciplined virtue) as spiritually efficacious; for householders and rulers, the implication is that self-restraint, vows, and dharmic conduct invite divine support and stabilize society.
No direct Vāstu rule appears here, but the iconographic marker “four-armed, radiant, divine form” supports pratima-lakṣaṇa (image-identification) used in temple worship and consecration contexts.
