Even before that, the action an injunction prescribes is already gone — because caste-status and everything of that sort has been stripped away. Stripped away by the scriptures that begin "not gross," and by the certainty: That is you — you alone.
Close to the Sanskrit
Even beforehand this action of injunction [ceases], because of the removal of caste-hood and the rest; that [removal follows] from the scriptures beginning "not gross," and from the certainty "That you alone are."
