Matsya Purana — Indra Sends Soma to Battle: Frost-Weapon
त्वं मत्तः प्रतिवीर्यश्च ज्योतिषां चेश्वरेश्वरः त्वन्मयं सर्वलोकेषु रसं रसविदो विदुः //
tvaṃ mattaḥ prativīryaśca jyotiṣāṃ ceśvareśvaraḥ tvanmayaṃ sarvalokeṣu rasaṃ rasavido viduḥ //
You are the countervailing power to me, and the Lord of lords even among the shining celestial beings. In all worlds, the wise connoisseurs of essence know the very ‘rasa’ (inner sap/essence) to be permeated by You—made of You.
It frames the Supreme (Matsya/Vishnu) as the inner essence present across all worlds and superior even to celestial powers—an idea that underlies Pralaya teachings: the cosmos changes, but the divine essence remains the ground of all.
By asserting that all ‘rasa’ (value/essence) is God-pervaded, it encourages rulers and householders to govern and live with humility, restraint, and devotion—seeing worldly power and pleasures as meaningful only when aligned with the Supreme.
No direct Vastu or temple-measurement rule appears here; its ritual takeaway is theological: worship is meaningful because the deity is the indwelling essence (tvanmaya) of all realms, supporting consecration and offering rites as communion with the universal Lord.
