Matsya Purana — The Greatness and Procedure of the Sarva-Phala-Tyaga Vrata
यथा फलेषु सर्वेषु वसन्त्यमरकोटयः तथा सर्वफलत्यागव्रताद्भक्तिः शिवे ऽस्तु मे //
yathā phaleṣu sarveṣu vasantyamarakoṭayaḥ tathā sarvaphalatyāgavratādbhaktiḥ śive 'stu me //
As countless hosts of the immortals abide within all fruits, so may devotion to Śiva arise in me through the vow of renouncing every self-seeking fruit of action.
It does not describe pralaya directly; instead, it uses a cosmological-style analogy (countless devas abiding within all “fruits”) to stress an inner spiritual principle: renouncing attachment to results becomes a cause for the rise of devotion to Śiva.
It promotes niṣkāma-dharma: performing one’s duties while relinquishing claim over outcomes. For a king or householder, this means governing, giving, and performing rites without greed for reward—transforming action into Śiva-oriented devotion.
The ritual significance is the vrata principle itself—“sarvaphala-tyāga” (abandoning all fruits). It functions as a devotional discipline: offerings and duties are performed with inner renunciation, culminating in bhakti toward Śiva rather than merit-calculation.
