। ॥ ५५० ॥
In plain words
This body of his, though he's free of it, just remains - like the skin a snake has already shed. It gets moved a little this way, a little that way, only by the breath still passing through it, nothing more.
Close to the Sanskrit
But this body of the liberated one remains like the sloughed-off skin of a snake, moved here and there, however slightly, by the mere life-breath.
