। ॥ ५५७ ॥
In plain words
Wherever this body of the ascetic who has become Brahman happens to crumble - like a leaf falling from its tree, it hardly matters where - that body, in truth, was already burnt to nothing by the fire of knowledge, long before it ever fell.
Close to the Sanskrit
Wherever the body of the yati who has become Brahman falls apart at its falling, like a leaf from a tree - that [body], indeed, was already burnt by the fire of consciousness even before that.
