There should be a word of warning about the folly of trying to reach spiritual illumination by artificial methods. Astral sight is sometimes quickly developed by crystal gazing and also by a certain regulation of the breathing. For two reasons such methods should be avoided. One is that any powers thus gained can not be permanent, and the other is that they may be more or less dangerous. Many people have made physical wrecks of themselves or have become insane by some of these methods.
There are those who advertise to quickly teach clairvoyance, for a consideration, as though spiritual powers could really be conferred instead of evolved! It is true that efforts toward the evolution of such powers may be enormously aided by teachers, but such instruction can not be bought, and the offer to furnish it for money is the best evidence of its worthlessness. Those who teach this ancient wisdom select their own pupils from the morally fit, and tuition can be paid only in devotion to truth and service to humanity. That is the only road that leads to instruction worth having, and until the aspirant is firmly upon that sound moral ground he is much better off without powers, the selfish use of which would lead to certain disaster.
But how shall the pupil find the teacher? He need not find him, at first, so far as the limited consciousness is concerned. Long before he knows anything of it in his waking hours he may be receiving instruction while he is out of the physical body during the hours of sleep. The teacher finds the pupil long before the pupil suspects that the teacher exists; and since it is the pupil who has the limited consciousness it is quite natural that it should be so. Thus it is inevitable that all who enter upon the way that leads to spiritual illumination must long remain ignorant of the fact that any teachers are interested in them or that anybody is giving the slightest attention to them. Naturally enough one cannot know until the moment arrives when his brain has become sufficiently sensitive to retain a memory of at least a fragment of his superphysical experiences.
