"The Masters and the Brotherhood. All this while, the Adept, besides using his pupil as an apprentice, has been preparing him for presentation to the Great White Brotherhood for Initiation. The whole object of the existence of that Brotherhood is to promote the work of evolution, and the Master knows that when the pupil is ready for the stupendous honour of being received as a member of it, he will be of very much more use in the world than before. Therefore it is His wish to raise his pupil to that level as soon as possible."
