विश्वमूर्तिर्महामूर्तिर्दीप्तमूर्तिरमूर्तिमान् ।अनेकमूर्तिरव्यक्तः शतमूर्तिः शताननः ॥ ९० ॥

In plain words

The universe is his form. The form is vast. The form is blazing light — and he has no form at all. His forms are countless; he is Avyakta, never once appearing. A hundred forms. A hundred faces.

Close to the Sanskrit

He whose form is the universe, he whose form is vast, he whose form is blazing, he who possesses no form; he whose forms are many, the unmanifest, he of a hundred forms, he of a hundred faces.
