Śaṅkarācārya's commentary

The Unmanifested (Avyakta) is the sleeping condition of the Prajāpati who is asleep. Out of That, all manifestations (vyaktis), all creatures, unmoving and moving (sthāvara and jaṅgama), are manifested at the coming on of day, i.e., when Brahmā awakes. So, at the coming on of night, i.e., when Brahmā goes to sleep, all the manifestations dissolve there only, in what is called Avyakta, the one already spoken of.
