People should not worry so much about what they do but rather about what they are. If they and their ways are good, then their deeds are radiant. If you are righteous, then what you do will also be righteous. We should not think that holiness is based on what we do but rather on what we are, for it is not our works which sanctify us but we who sanctify our works. However holy our works may be, they do not in any way make us holy in so far as they are works, but it is we, in so far as we are holy and possess fullness of being, who sanctify all our works, whether these be eating, sleeping, waking or anything at all.
