Matsya Purana — The Greatness of Prayaga and the Supremacy of Cow-Donation
ततः शुभानि कर्माणि चिन्तयानः पुनः पुनः गुणवान्वित्तसम्पन्नो भवतीह न संशयः //
tataḥ śubhāni karmāṇi cintayānaḥ punaḥ punaḥ guṇavānvittasampanno bhavatīha na saṃśayaḥ //
Therefore, one who repeatedly reflects upon auspicious deeds becomes, in this very life, endowed with virtue and possessed of wealth—of this there is no doubt.
This verse does not address Pralaya directly; it teaches a dharmic principle that sustained contemplation and practice of auspicious actions yields virtue and prosperity in this life.
It supports the king’s and householder’s dharma: repeatedly intending and choosing śubha-karmas (charity, protection, truthfulness, restraint, ritual duty) cultivates good qualities and stable prosperity, strengthening both personal conduct and social order.
No specific Vastu or iconographic rule is stated; the ritual takeaway is that consistent mindful orientation toward auspicious acts (śubha-karmas) is itself presented as a generator of merit and worldly well-being.
