Śaṅkarācārya's commentary

This multitude of beings comprising those that move as well as those that do not — the same multitude that existed in the preceding kalpa or age, and no other — involuntarily comes into being at the coming on of day, and is dissolved again at the coming on of night, at the close of the day. Again, at the coming on of day, it involuntarily comes into existence.
