Those who know a day of Brahman to end after one thousand ages, and the night to terminate after one thousand ages, are the persons who know day and night. On the advent of day, all perceptible things are produced from the unperceived; and on the advent of night they dissolve in that same (principle) called the unperceived. This same assemblage of entities, being produced again and again, dissolves on the advent of night, and, O son of Pritha! issues forth on the advent of day, without a will of its own.
