Vaṃśānuvārṇana and the Transition to the Fourth (Upasaṃhāra) Pada
अन्ते ऽनेकयुगे तस्मिन्क्षीणे संहार उच्यते / सप्तैते भार्गवा देवा अन्ते मन्वन्तरे तदा
ante 'nekayuge tasminkṣīṇe saṃhāra ucyate / saptaite bhārgavā devā ante manvantare tadā
At the end of many yugas, when that span is spent, it is called saṃhāra, the dissolution. Then, at the close of the manvantara, these seven Bhārgava deities appear.
