Verse 57

सति विस्तारजे तस्मिन्ब्रह्मेदमिति वेद्म्यहम् ।त्वमहंत्वादिबाधे तत्सदित्यादि जगद्गतम्

In plain words

When that state, born of [its own] expansion, obtains, I know: 'This is Brahman.' In the negation of thou-ness, I-ness, and the rest, [the truth] 'that is real,' and so on, pervades the world.
