Matsya Purana — Inquiry into Yayāti’s Story and the Kacha–Devayānī Episode
*शुक्र उवाच आचक्षे वो दानवा बालिशाः स्थ शिष्यः कचो वत्स्यति मत्समीपे संजीवनीं प्राप्य विद्यां मयायं तुल्यप्रभावो ब्राह्मणो ब्रह्मभूतः //
*śukra uvāca ācakṣe vo dānavā bāliśāḥ stha śiṣyaḥ kaco vatsyati matsamīpe saṃjīvanīṃ prāpya vidyāṃ mayāyaṃ tulyaprabhāvo brāhmaṇo brahmabhūtaḥ //
Śukra said: “I tell you, O Dānavas—you are foolish. My disciple Kaca will dwell close by me; having obtained from me the knowledge of Saṃjīvanī, this brāhmaṇa will become equal to me in power, as one who has attained Brahman.”
This verse does not address Pralaya; it belongs to an ethical–mythic episode about acquiring the Saṃjīvanī vidyā, emphasizing how sacred knowledge can confer extraordinary power.
Indirectly, it highlights discernment and restraint: power gained through learning and proximity to a teacher should be respected, and rash actions (here, the Dānavas’ foolishness) lead to strategic disadvantage—an instructive principle for rulers and householders alike.
No Vāstu or temple-architecture rule is stated here; the ritual significance is the Saṃjīvanī as a specialized vidyā/mantra tradition transmitted through guru–disciple lineage.
