। ॥ २५ ॥
In plain words
Viṣṇu is Cit, pure consciousness, one undivided essence; his very Svarūpa is the oneness of Brahman and Ātman. In that, the world rises only through misperception, like a snake imagined in a rope.
Close to the Sanskrit
In Viṣṇu, of the single essence of Cit—consciousness alone—whose Svarūpa is the identity of Brahman and Ātman, the world has arisen through delusion alone, as the illusion of a snake in a rope.
