Matsya Purana — The Pushkara Manifestation
वरं वै प्रथमं देवं द्वितीयं ध्रुवमव्ययम् विश्वावसुं तृतीयं च चतुर्थं सोममीश्वरम् //
varaṃ vai prathamaṃ devaṃ dvitīyaṃ dhruvamavyayam viśvāvasuṃ tṛtīyaṃ ca caturthaṃ somamīśvaram //
First, one should place (or worship) the deity Vara; second, Dhruva, the imperishable; third, Viśvāvasu; and fourth, Soma, the sovereign Lord.
This verse is not about pralaya; it gives a ritual/iconographic sequence of specific deities (Vara, Dhruva, Viśvāvasu, Soma) to be placed or worshipped in order.
It supports the king/householder duty of maintaining correct public and domestic worship—following prescribed devata-order (krama) is presented as part of dharmic ritual discipline.
It indicates a prescribed ordering for installation/worship (devata-krama), relevant to temple layout planning and consecration rites where deities are assigned positions and honored sequentially.
