Matsya Purana — Solar Dynasty Prelude: Vivasvān–Saṃjñā–Chāyā
जगामोपवनं शम्भोर् अश्वाकृष्टः प्रतापवान् कल्पद्रुमलताकीर्णं नाम्ना शरवणं महत् //
jagāmopavanaṃ śambhor aśvākṛṣṭaḥ pratāpavān kalpadrumalatākīrṇaṃ nāmnā śaravaṇaṃ mahat //
Drawn onward by his horse, the mighty and radiant one went to Śambhu’s sacred grove—an expansive woodland called Śaravaṇa, thickly overgrown with creepers of wish-fulfilling trees.
This verse does not discuss Pralaya; it focuses on a narrative movement toward Śiva’s sacred grove, highlighting sacred geography rather than cosmic dissolution.
Indirectly, it reflects the Purāṇic ideal of approaching sacred places (tīrtha/upavana) for merit and guidance—an act recommended for rulers and householders as part of dharmic life and pilgrimage-based purification.
The ritual significance lies in the setting: an upavana (sacred grove) associated with Śiva, a common Purāṇic locus for worship, vows, and tīrtha practices; no explicit Vāstu or temple-construction rule is stated in this verse.
