Matsya Purana — The Syamantaka Jewel Episode and the Vrishni–Sainya Genealogies
प्रसेनस्तु गतो ऽरण्यं मणिरत्नेन भूषितः तं दृष्ट्वा स हतस्तेन गोविन्दः प्रत्युवाच ह हन्मि चैनं दुराचारं शत्रुभूतं हि वृष्णिषु //
prasenastu gato 'raṇyaṃ maṇiratnena bhūṣitaḥ taṃ dṛṣṭvā sa hatastena govindaḥ pratyuvāca ha hanmi cainaṃ durācāraṃ śatrubhūtaṃ hi vṛṣṇiṣu //
Prasena went into the forest, adorned with that jewel-gem. Seeing that he had been slain because of it, Govinda spoke out: “I shall kill this wicked one, for he has become an enemy among the Vṛṣṇis.”
Nothing directly—this verse belongs to a dynastic-Krishna narrative (the Syamantaka jewel episode), focusing on conflict and moral culpability rather than cosmic creation or Pralaya.
It frames a dharmic concern: when wrongdoing turns someone into a threat to the community (“enemy among the Vṛṣṇis”), the righteous leader is expected to investigate and restrain the evil-doer—ideally through just action rather than impulse.
No Vāstu, temple-building, or ritual procedure is stated here; the verse centers on the jewel-driven tragedy and Govinda’s resolve within the Vrishni clan.
