Matsya Purana — Tārakāsura’s Austerity and Boon; Mobilization for War; Bṛhaspati’s Fourfold P...
ततः संचिन्त्य दैत्येन्द्रः शिशोर्वै सप्तवासरात् वव्रे महासुरो मृत्युम् अवलेपेन मोहितः //
tataḥ saṃcintya daityendraḥ śiśorvai saptavāsarāt vavre mahāsuro mṛtyum avalepena mohitaḥ //
Then the lord of the Daityas, after reflecting, that great Asura—deluded by arrogance—chose death at the hands of the child within seven days.
This verse is not about cosmic dissolution; it illustrates moral causality—how delusion born of pride can lead a powerful being to choose self-destructive outcomes.
It warns against avalepa (haughty pride): rulers and householders should practice humility and clear judgment, because arrogance clouds discernment and turns power into ruin.
No Vastu or ritual procedure is stated in this verse; its primary focus is narrative ethics—boon-choices, time-bound fate (seven days), and the peril of pride.
