Matsya Purana — Manifestation of Kauśikī
स्यामहं काञ्चनाकारा वाल्लभ्येन च संयुता भर्तुर्भूतपतेरङ्गम् एकतो निर्विशे ऽङ्गवत् //
syāmahaṃ kāñcanākārā vāllabhyena ca saṃyutā bharturbhūtapateraṅgam ekato nirviśe 'ṅgavat //
“I was dark-complexioned, yet golden in form, and endowed with belovedness. From one side, I entered the body of my husband—Bhūtapati, Lord of beings—as though becoming a limb of his.”
This verse does not describe pralaya directly; it emphasizes a mythic, symbolic union—an individual merging into Bhūtapati (Śiva)—used in Purāṇic storytelling to convey divine integration rather than cosmic dissolution.
Indirectly, it highlights ideals of marital unity and devotion (saṃyutā, vāllabhya) presented as sacred archetypes; in Purāṇic ethics these motifs support household dharma through fidelity, harmony, and shared identity in righteous living.
No explicit Vāstu or ritual procedure is stated; however, the imagery of “entering the deity’s body like a limb” can align with iconographic/theological ideas of inseparability between deity and śakti in temple theology, though this verse itself is narrative rather than technical.
