Varāha-uddhāraṇa and the Re-constitution of Bhū-maṇḍala
Earth after Pralaya
कालः कृतयुगे त्वेष तस्य सन्ध्यां निबोधत / चत्वारि तु सहस्राणि वर्षाणां तत्कृतं युगम्
kālaḥ kṛtayuge tveṣa tasya sandhyāṃ nibodhata / catvāri tu sahasrāṇi varṣāṇāṃ tatkṛtaṃ yugam
This is the measure of time for the Kṛtayuga; know also its sandhyā, the twilight junction. The Kṛtayuga consists of four thousand years.
