12.4.1

/0 śrī-śuka uvāca
kālas te paramāṇv-ādir dvi-parārdhāvadhir nṛpa /
kathito yuga-mānaṃ ca śṛṇu kalpa-layāv api //

1. Sri Suka said:—Time in all its aspects commencing with Paramanu or the minutest division and ending with Dviparardha (the two halves of the Divine century making the period of Brahma’s life), O king,—Time has been described, as also the extent of a Yuga (Age); and now hear also of the periods of Kalpa and Laya (subsistence and dissolution).
