Matsya Purana — Description of Gomedaka and Puṣkara Dvīpas; the Lokāloka Boundary; Ocean Tide...
*सूत उवाच गोमेदकं प्रवक्ष्यामि षष्ठं द्वीपं तपोधनाः सुरोदकसमुद्रस्तु गोमेदेन समावृतः //
*sūta uvāca gomedakaṃ pravakṣyāmi ṣaṣṭhaṃ dvīpaṃ tapodhanāḥ surodakasamudrastu gomedena samāvṛtaḥ //
Sūta said: “I shall now describe Gomedaka, the sixth dvīpa, O ascetics rich in austerity. The ocean called Surodaka, the sea of sacred waters, is encircled by Gomedaka.”
This verse is not about Pralaya; it belongs to the Matsya Purana’s cosmographic mapping of the world (dvīpas and encircling oceans), describing how Gomedaka surrounds the Surodaka ocean.
Directly, it does not prescribe duties; indirectly, Purāṇic cosmography frames dharma by situating human society within a sacred, ordered universe—useful for kingship ideology and household ritual orientation toward the wider cosmic order.
No explicit Vāstu or temple rule appears here; the ritual takeaway is the Purāṇic idea of sacred waters (Surodaka) and cosmological orientation, which later traditions sometimes mirror in temple and pilgrimage symbolism.
