"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 am a brother of yours, who has travelled 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... The books that I have written are sent out with no claim for their acceptance. They may, or may not, be correct, true and useful. It is for you to ascertain their truth... Neither I nor A.A.B. is the least interested in having them acclaimed as inspired writings, or in having anyone speak of them (with bated breath) as being the work of one of the Masters. If... the information given raises the aspiration and the will-to-serve from the plane of the emotions to that of the mind (the plane whereon the Masters can be found) then they will have served their purpose... 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."
