Matsya Purana — The Syamantaka Jewel Episode and the Vrishni–Sainya Genealogies
ततस्ते यादवाः सर्वे वासुदेवमथाब्रुवन् अस्माकं तु मतिर्ह्यासीत् प्रसेनस्तु त्वया हतः //
tataste yādavāḥ sarve vāsudevamathābruvan asmākaṃ tu matirhyāsīt prasenastu tvayā hataḥ //
Then all those Yādavas said to Vāsudeva: “Indeed, our belief was that Prasena had been slain by you.”
This verse does not discuss pralaya; it belongs to a dynastic-legend narrative where the Yādavas voice suspicion about Prasena’s death.
It highlights a moral-social theme: communities can form judgments on incomplete information; dharmic conduct requires careful inquiry and evidence before accusing a leader or kinsman of wrongdoing.
No Vāstu, temple-building, or ritual procedure is stated in this verse; it focuses on dialogue within a clan dispute involving Vāsudeva and Prasena.
