Matsya Purana — Kailasa
सिक्त्वा पर्वतमेरुं सा गत्वा विद्याधरानपि शैमिमण्डलकोष्ठं तु सा प्रविष्टा महत्सरः //
siktvā parvatameruṃ sā gatvā vidyādharānapi śaimimaṇḍalakoṣṭhaṃ tu sā praviṣṭā mahatsaraḥ //
After bathing (or sprinkling with sacred water) at Mount Meru, she went on even to the realm of the Vidyādharas; then she entered the great lake, into the chambered enclosure of the Śaimi-maṇḍala.
It situates the narrative in a mythic-cosmic landscape (Meru, celestial Vidyādharas, a great lake), a common Purāṇic way of describing the world’s sacred regions during the flood-era account rather than giving a direct technical description of dissolution.
Indirectly, it reflects the Purāṇic ideal of moving through sanctified spaces and observing purity rites (bathing/sprinkling), which parallels household and royal dharma practices of ritual cleanliness and reverence for tīrthas.
The terms suggest ritual purification (siktvā) and a bounded precinct (koṣṭha) within a defined circle/zone (maṇḍala), echoing how maṇḍala and enclosed spaces are treated as consecrated, ordered areas—concepts later central to Vāstu and ritual layout.
