Matsya Purana — The Syamantaka Jewel Episode and the Vrishni–Sainya Genealogies
प्रसेनं तु हतं ज्ञात्वा गोविन्दः परिशङ्कितः गोविन्देन हतो व्यक्तं प्रसेनो मणिकारणात् //
prasenaṃ tu hataṃ jñātvā govindaḥ pariśaṅkitaḥ govindena hato vyaktaṃ praseno maṇikāraṇāt //
When it was learned that Prasena had been slain, Govinda became an object of suspicion; people were certain that Govinda had killed Prasena, and that the motive was the jewel.
This verse is not about Pralaya; it belongs to a royal-legend narrative where social suspicion arises after a death connected to a powerful jewel.
It highlights a dharmic concern central to governance and household ethics: public perception, false accusation, and the need for clear investigation when wealth (a jewel) becomes the suspected motive for violence.
No Vastu, temple-architecture, or ritual procedure is stated in this verse; its focus is narrative—suspicion and motive centered on the possession of a jewel.
