Yuga-Vibhāga and Kāla-Pramāṇa
Measures of Time and the Four Yugas
भूतभव्यानि यानीह वर्त्तमानानि यानि च / त्रेतायुगे च तान्यत्र जायन्ते चक्रवर्त्तिनः
bhūtabhavyāni yānīha varttamānāni yāni ca / tretāyuge ca tānyatra jāyante cakravarttinaḥ
Whatever is of the past and the future, and whatever is present here—there, in the Tretā Yuga, all that is born as cakravartin rulers.
