। ॥ ५०२ ॥
In plain words
It is the body-mind, and only the body-mind, that comes and goes, that acts and reaps the results, that lives and dies. I remain exactly where I always am - unmoving, like a great mountain that nothing can shift.
Close to the Sanskrit
The limiting adjunct comes, that same one goes, that same one performs and enjoys actions, that same one lives and dies; I, always, remain utterly unmoving, like the Kula mountain.
