The movement inward is all to the good—for going inward if one goes far enough brings one to the psychic. The more peace there is the better; even if it is only a little at first, that is so much gained. If the inward-drawing movement is held to, it will grow and the power to reject anger and other such movements will increase. It is this peace and inward psychic movement in you that we shall try for till it is done.
