Matsya Purana — Yadu Lineage
*सूत उवाच पुरुषः कश्यपस्त्वासीद् अदितिस्तु प्रिया स्मृता ब्रह्मणः कश्यपस्त्वंशः पृथिव्यास्त्वदितिस्तथा //
*sūta uvāca puruṣaḥ kaśyapastvāsīd aditistu priyā smṛtā brahmaṇaḥ kaśyapastvaṃśaḥ pṛthivyāstvaditistathā //
Sūta said: “Kashyapa indeed was the male progenitor, and Aditi is remembered as his beloved. Kashyapa was a portion (emanation) of Brahmā, and likewise Aditi was a portion of the Earth (Pṛthivī).”
It presents a creation-and-lineage (sarga/vamsha) idea: Kashyapa arises as an emanation of Brahmā and Aditi as an emanation of Earth—framing beings as born from cosmic principles rather than describing pralaya directly.
By grounding social and cosmic order in sacred genealogy, it supports the Purāṇic ethic that kings and householders uphold dharma through lineage-conscious rites—especially honoring progenitors (pitṛs) and maintaining orderly succession.
No direct Vāstu rule appears here; the ritual takeaway is genealogical sanctification—useful for lineage-invocations (saṅkalpa, pravara-style remembrance) where origins of progenitors are recited.
