Yuga-Vibhāga and Kāla-Pramāṇa
Measures of Time and the Four Yugas
सूत उवाच पृथिव्यादिप्रसंगेन यन्मया प्रागुदीरितम् / तेषां चतुर्युगं ह्येतत्तद्वक्ष्यामि निबोधत
sūta uvāca pṛthivyādiprasaṃgena yanmayā prāgudīritam / teṣāṃ caturyugaṃ hyetattadvakṣyāmi nibodhata
Sūta said: What I earlier mentioned in connection with the earth and related matters—this is their four-yuga cycle; now I shall explain it, listen attentively.
