ततः सुरान्विजेष्यामो भोक्ष्यामो ऽथ जगत्त्रयम् स्थिरोपायो हि पुरुषः स्थिरश्रीरपि जायते //
tataḥ surānvijeṣyāmo bhokṣyāmo 'tha jagattrayam sthiropāyo hi puruṣaḥ sthiraśrīrapi jāyate //
“Then we shall conquer the gods, and thereafter enjoy the three worlds. For a man who is steadfast in his means (and strategy) becomes possessed of enduring prosperity as well.”
This verse does not address pralaya or cosmogony; it focuses on worldly power—conquest and the claim to rule the three worlds—linking success to steadfast strategy.
It highlights a Rajadharma principle in a value-neutral, political sense: stability of method (sthira-upāya) produces stable prosperity (sthira-śrī). In ethical readings, a king’s “firm means” should be disciplined policy and consistent governance rather than impulsive action.
No vāstu, temple-iconography, or ritual procedure is mentioned; the takeaway is strategic steadiness as a general principle, not a technical architectural rule.
