। ॥ ९७ ॥
In plain words
The mind lets go of its own churning and simply rests as Reality and nothing else. That resting is the highest peace — and its mark is nirvāṇa in Brahman, the separate flame gone out.
Close to the Sanskrit
Having completely abandoned its own modification, the abiding of the mind in the mode of Reality alone — that is the highest peace, characterized by extinction in Brahman.
