Prajāpati-vaṃśānukīrtana — Genealogical Enumeration of Progenitors
Dharma’s Line and the Sādhyas
प्राप्ते प्राप्ते तु कल्पान्ते रुद्रः संहरति प्रजाः / कालो भूत्वा युगात्मासौ रुद्रः संहरते पुनः
prāpte prāpte tu kalpānte rudraḥ saṃharati prajāḥ / kālo bhūtvā yugātmāsau rudraḥ saṃharate punaḥ
Whenever the end of a Kalpa arrives, Rudra withdraws and destroys the beings; becoming Time, the very soul of the Yuga, that Rudra destroys again.
