Yuga-Vibhāga and Kāla-Pramāṇa
Measures of Time and the Four Yugas
सिंहातङ्का महासत्त्वा मत्तमातङ्गगमिनः / महाधनुर्द्धराश्चैव त्रेतायां चक्रवर्त्तिनः
siṃhātaṅkā mahāsattvā mattamātaṅgagaminaḥ / mahādhanurddharāścaiva tretāyāṃ cakravarttinaḥ
Lion-like in awe, great in spirit, moving with the gait of a rutting elephant; bearing mighty bows, they are, in the Tretā age, cakravartins—universal sovereigns.
