"In approaching the physical body of the Master, the pupil advances into that glowing globe of finer material, and when he finally reaches the feet of his Master he is already in the heart of that splendid sphere; and when the Master embraces the neophyte as described above, and expands himself to include the aura of the pupil, it is really the central heart of fire which so expands and includes him, for all through the ceremony of acceptance he is already far within the outer ring of that mighty aura. Thus for a few moments they two are one, and not only does the Master’s aura affect that of the pupil as described above, but any special characteristics attained by the latter act upon the corresponding centres of the Master’s aura, and that flashes out in response."
