We always try to see God in some abstruse, abstract way, not realising that most often, or perhaps always, God presents himself to us only in a form in which we can recognize Him. That is the human form. So when Masters come to us, it is the Almighty Himself who comes to us. It is in a form which we can recognize, in a form which we can learn to love, from which we can receive our teachings. So, that is another great function of Masters when they come to us in their physical form.
