saḥ — He (the Supreme Personality of Godhead); īśvaraḥ — the supreme controller; kālaḥ — the time factor; urukramaḥ — the Lord, whose every action is uncommon; asau — that one; ojaḥ — the strength of the senses; sahaḥ — the strength of the mind; sattva — steadiness; bala — bodily strength; indriya — and of the senses themselves; ātmā — the very self; saḥ — He; eva — indeed; viśvam — the whole universe; paramaḥ — the supreme; sva-śaktibhiḥ — by His multifarious transcendental potencies; sṛjati — creates; avati — maintains; atti — winds up; guṇa-traya-īśaḥ — the master of the material modes.
The Supreme Personality of Godhead, who is the supreme controller and time factor, is the power of the senses, the power of the mind, the power of the body, and the vital force of the senses. His influence is unlimited. He is the best of all living entities, the controller of the three modes of material nature. By His own power, He creates this cosmic manifestation, maintains it and annihilates it also.

Since the material world is being moved by the three material modes and since the Lord is their master, the Lord can create, maintain and destroy the material world.
