Matsya Purana — Inquiry into Taraka’s Slaying and the Prelude to Guha
ददौ स दश धर्माय कश्यपाय त्रयोदश सप्तविंशतिं सोमाय चतस्रो ऽरिष्टनेमये //
dadau sa daśa dharmāya kaśyapāya trayodaśa saptaviṃśatiṃ somāya catasro 'riṣṭanemaye //
“He allotted ten (daughters) to Dharma, thirteen to Kaśyapa, twenty-seven to Soma, and four to Ariṣṭanemi.”
This verse does not describe Pralaya; it records a genealogical/allotment enumeration, typical of creation-era ordering of beings and lineages rather than dissolution.
Indirectly, it supports dharma by preserving lineage knowledge (vaṃśa-smṛti), which a king and householders uphold through proper rites, ancestry remembrance, and social-religious continuity.
No Vāstu or temple-rule detail appears here; the ritual relevance is primarily genealogical—used to situate deities/sages in śrāddha, calendrical, and mythic frameworks (not construction guidelines).
