The only work that spiritually purifies is that which is done without personal motives, without desire for fame or public recognition or worldly greatness, without insistence on one’s mental motives or vital lusts and demands or physical preferences, without vanity or crude self-assertion or claim for position or prestige, done for the sake of the Divine alone. All work done in an egoistic spirit, however “good” for people in the world of the Ignorance is of no avail to the seeker and will keep the door shut to the Divine.
