These Elder Brothers of the human family are not spirits in the ordinary sense of the word, nor are they hazy beings, “gods” or “angels They are men, Mahatmas (Great Souls), who are perfected beings physically, mentally, morally, psychically, spiritually—who stand now where we shall one day stand, when we have perfected ourselves in the same way that They have done, through self-induced and self-devised exertions.
These Masters stand to us in Their knowledge and power, in Their ability and efforts to help and guide us, as the greatest and most powerful suggestion that could be made to any human being. They are willing and ready to help whenever and where ever we are willing and ready to receive. They never ask for anything; They are always ready to give to those who may be willing to follow the lines indicated, so that we in our turn may become as They are—may know for ourselves.
