Yuga-Vibhāga and Kāla-Pramāṇa
Measures of Time and the Four Yugas
ऋषयस्तपसा वेदान्द्वापरादिष्वधीयते / अनादिनिधिना दिव्याः पूर्वं सृष्टाः स्वयंभुवा
ṛṣayastapasā vedāndvāparādiṣvadhīyate / anādinidhinā divyāḥ pūrvaṃ sṛṣṭāḥ svayaṃbhuvā
The seers, by the power of austerity, study the Vedas in the Dvāpara and other ages. The Self-born, the divine Treasure without beginning, first created the celestial ṛṣis.
