"Suffice it to say, that I am a Tibetan disciple of a certain degree, and this tells you but little, for all are disciples from the humblest aspirant up to, and beyond, the Christ Himself. I live in a physical body like other men, on the borders of Tibet... I am a brother of yours, who has traveled a little longer upon the Path than has the average student, and has therefore incurred greater responsibilities. I am one who has wrestled and fought his way into a greater measure of light than has the aspirant who will read this article, and I must therefore act as a transmitter of the light, no matter what the cost... I have told you much; yet at the same time I have told you nothing which would lead you to offer me that blind obedience and the foolish devotion which the emotional aspirant offers to the Guru and Master Whom he is as yet unable to contact. Nor will he make that desired contact until he has transmuted emotional devotion into unselfish service to humanity... The books that I have written are sent out with no claim for their acceptance... Neither I nor A.A.B. is the least interested in having them acclaimed as inspired writings... If the statements meet with eventual corroboration, or are deemed true under the test of the Law of Correspondences, then that is well and good. But should this not be so, let not the student accept what is said."
