He thinks simply of the good of evolution as a whole.

This gives him a definite foothold and the clear criterion, and removes from him altogether the pain of indecision and hesitation.

The Will of the Deity is man's evolution; whatever therefore helps on that evolution must be good; whatever stands in the way of it and delays it, that thing must be wrong, even though it may have on its side all the weight of public opinion and immemorial tradition.
Knowing that the true man is the ego and not the body, he sees that it is the life of the ego only which is really of moment, and that everything connected with the body must unhesitatingly be subordinated to those higher interests.

He recognizes that this earth-life is given to him for the purpose of progress, and that that progress is the one important thing.

The real purpose of his life is the unfoldment of his powers as an ego, the development of his character.
