Matsya Purana — Cosmography of Śākadvīpa and Successive Dvīpas: Mountains
तस्यापरे चाम्बिकेयः सुमनाश्चैव स स्मृतः हिरण्याक्षो वराहेण तस्मिञ्छैले निषूदितः //
tasyāpare cāmbikeyaḥ sumanāścaiva sa smṛtaḥ hiraṇyākṣo varāheṇa tasmiñchaile niṣūditaḥ //
Among his other sons/descendants, Ambikeya and Sumanas are also remembered; and Hiraṇyākṣa was slain by Varāha—Viṣṇu in the Boar incarnation—upon that very mountain.
This verse does not describe pralaya directly; it preserves mythic-historical memory by linking Hiraṇyākṣa’s death to Viṣṇu’s Varāha incarnation, a narrative often associated with restoring cosmic order.
Indirectly, it presents the ideal of dharma-protection: just as Varāha destroys a disruptive force (Hiraṇyākṣa), a king is expected to remove threats to social and cosmic order; a householder supports that order through righteous conduct.
No explicit Vāstu or ritual procedure is taught here; the only locative detail is “on that mountain,” which functions as sacred geography rather than architectural instruction.
