avyaktāt — from the unmanifest; vyaktayaḥ — living entities; sarvāḥ — all; prabhavanti — become manifest; ahaḥ-āgame — at the beginning of the day; rātri-āgame — at the fall of night; pralīyante — are annihilated; tatra — into that; eva — certainly; avyakta — the unmanifest; saṁjñake — which is called.
At the beginning of Brahmā’s day, all living entities become manifest from the unmanifest state, and thereafter, when the night falls, they are merged into the unmanifest again.
