It is not so much that we have to change ourselves as to give up ourselves. We are so imperfect and faulty, so selfish and weak, so sinful and ignorant, that giving up our own selves means being more than willing to part with what is not worth keeping. But to what are we to give them up and how are we to do it? We are to invoke the higher self, request it daily to take possession of our hearts, minds, and wills, and to strive actively to purify them. Much of our striving will be in the form of surrendering egoistic thoughts, impulses, and feelings by crushing them at the moment of birth. In that way we slowly give up our inner selves and submit the conduct of our outer selves to a higher will.
