"This august body is often called the Great White Brotherhood, but its members are not a community all living together. Each of Them, to a large extent, draws Himself apart from the world, and They are in constant communication with one another and with Their Head; but Their knowledge of higher forces is so great that this is achieved without any necessity for meeting in the physical world. In many cases They continue to live each in His own country, and Their power remains unsuspected among those who live near Them. Any man who will may attract Their attention, but he can do it only by showing himself worthy of Their notice. None need fear that his efforts will pass unnoticed; such oversight is impossible, for the man who is devoting himself to service such as this, stands out from the rest of humanity like a great flame in a dark night. A few of these great Adepts, who are thus working for the good of the world, are willing to take as apprentices those who have resolved to devote themselves utterly to the service of mankind; such Adepts are called Masters."
