Yuga-Vibhāga and Kāla-Pramāṇa
Measures of Time and the Four Yugas
इतरेषु ससंध्येषु ससंध्यांशेषु च त्रिषु / एकन्यायेन वर्तन्ते सहस्राणि शतानि च
itareṣu sasaṃdhyeṣu sasaṃdhyāṃśeṣu ca triṣu / ekanyāyena vartante sahasrāṇi śatāni ca
In the other three Yugas as well, together with their saṃdhyā and saṃdhyāṃśa, the thousands and hundreds proceed by the same single rule.
