Matsya Purana — Omens in Tripura and the Nārada–Maya Dialogue on Dharma
शूराः स्थ जातपुत्राः स्थ कृतकृत्याः स्थ दानवाः युध्यध्वं दैवतैः सार्धं कर्तव्यं चापि नो भयम् //
śūrāḥ stha jātaputrāḥ stha kṛtakṛtyāḥ stha dānavāḥ yudhyadhvaṃ daivataiḥ sārdhaṃ kartavyaṃ cāpi no bhayam //
O Dānavas, you are heroes; you have begotten sons; you are men who have accomplished your aims. Fight together with the gods—this is your duty, and for us there is no fear.
Nothing directly—this verse is a martial exhortation in a Deva–Dānava conflict and does not address pralaya or cosmological dissolution.
It emphasizes kartavya (duty) and fearlessness in undertaking one’s appointed role; by analogy, kings are urged to uphold their responsibilities with courage, and householders to perform obligations without wavering.
None explicitly—there is no Vāstu, temple-building, iconography, or ritual procedure referenced in this shloka.
