English
The period of the duration of the Prakrita creation is said to be a day of Brahma. There is a similar period constitut- ing the night. The lord effects creation during day time and dissolution during the night. He has neither a day nor a night (as we understand the terms). The time-duration by day and night is used in a secondary sense.
