Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
शरैर्यथा कुचरितैः प्रख्यातं परमागतम् सुनिर्मलं क्रमायातं कुपुत्रः स्वं महाकुलम् //
śarairyathā kucaritaiḥ prakhyātaṃ paramāgatam sunirmalaṃ kramāyātaṃ kuputraḥ svaṃ mahākulam //
Just as arrows, when wrongly aimed, can strike down what is famed and inherited from the highest ancestors, so too does a wicked son destroy his own great lineage, though it has come down in pure repute through an unbroken succession.
This verse is not about cosmic pralaya; it uses a worldly analogy (misdirected arrows) to describe the moral “ruin” of a family’s inherited fame through misconduct.
It warns that dharma and self-restraint protect kula (lineage) and kīrti (reputation). For householders, raising virtuous children is a duty; for kings, ensuring right conduct in heirs and administration preserves dynastic legitimacy.
No Vastu or ritual procedure is stated here; the teaching is ethical—highlighting how inherited purity of reputation can be quickly ruined by a single person’s wrongdoing.
