। ॥ ९७७ ॥
In plain words
The one for whom the body and all that comes with it simply is not; the one in whom the certainty stands unshaken — Brahman; the one filled full with supreme ānanda: that one is called jīvanmukta, free while still alive.
Close to the Sanskrit
He for whom the body and the rest do not exist, he for whom there is the certainty 'Brahman', who is full of supreme bliss — he is called liberated while living.
