Matsya Purana — The Greatness and Procedure of the Sarva-Phala-Tyaga Vrata
*नन्दिकेश्वर उवाच फलत्यागस्य माहात्म्यं यद्भवेच्छृणु नारद यदक्षयं परं लोके सर्वकामफलप्रदम् //
*nandikeśvara uvāca phalatyāgasya māhātmyaṃ yadbhavecchṛṇu nārada yadakṣayaṃ paraṃ loke sarvakāmaphalapradam //
Nandikeśvara said: “O Nārada, listen to the greatness of renouncing the fruits of one’s actions; by it there arises in the next world an imperishable, supreme reward, bestowing the results of all rightful desires.”
This verse does not address pralaya; it teaches a dharma principle: selfless action through renouncing the fruits yields an imperishable (akṣaya) spiritual reward.
It frames an ethical rule for rulers and householders alike: perform duties and public works without attachment to personal gain; such phala-tyāga is said to generate lasting merit and rightful fulfillment.
No specific Vāstu or iconographic rule is stated; however, the principle applies to rituals and temple/charity acts—offering the “fruit” of rites or donations selflessly is presented as producing akṣaya merit.
