In plain words
In the beginning, this universe was Brahman indeed. And it knew only itself: 'I am Brahman.' Therefore, it became all. Whosoever among the gods awakened to this, he indeed became that; likewise among the seers, and likewise among men. Seeing this very truth, the sage Vamadeva proclaimed: 'I was Manu, and the sun.' And even today, whoever thus knows 'I am Brahman' becomes this entire universe. Not even the gods can prevent him from being free, for he becomes their very Self. But he who worships another deity, thinking 'He is one and I am another,' does not know the truth; he is like a domestic animal to the gods. Just as many cattle serve a human being, so does every ignorant person sustain the gods through ritual. When even a single beast is taken away, it brings pain to the owner—how much more when many are taken! Therefore, the gods are not pleased that human beings should know this truth.
Close to the Sanskrit
Brahman indeed this in the beginning was. That knew its Self only: 'I am Brahman' thus. Therefore that became all. That whoever of the gods awakened, that indeed became that; similarly of seers, similarly of men. That indeed seeing this the seer Vamadeva attained: 'I was Manu and the sun' thus. That this also now, who thus knows 'I am Brahman' thus, he becomes all this. Of him not even the gods are capable of non-prosperity. The Self indeed of these he becomes. Now, who worships another deity, 'Other is that, other am I' thus, he knows not. Like a beast indeed he is of the gods. As indeed many beasts serve a man, so each person sustains the gods. In a single animal being taken away, it is displeasing; how much more in many! Therefore this is not dear to them, that men should know this.
