I heartily endorse the facts of these teachings, and pronounce them fundamentally correct. And, in this connection, I may say that every healer may apply his own methods PLUS this teaching regarding the aura, and thus obtain greatly increased results. By the faithful, persevering, holding in mind of certain ideas and feelings, the individual may flood his aura with the vibrations and colors of such ideas and feelings, and thus charge it with auric energy and power. By so doing, he gains the benefit of the reaction upon his own mind, and also secures the advantage of the effect thereof upon other persons with whom he comes in contact. In this way he not only builds up his individual character along desirable lines, but at the same time develops a strong, positive, attractive "personality" which affects others with whom he comes in contact. I do not consider it necessary to go into details here regarding this phase of "holding the thought," for, as I have said, the average student is already familiar with the rules regarding the same. In a nutshell, however, I will say that each individual is largely the result of the thoughts he has manifested, and the feelings which he has harbored. Therefore, the rule is to manifest and exercise the faculties you would develop, and inhibit or refrain from manifesting the ones you would restrain or control. Again, to restrain an undesirable faculty, develop and exercise its opposite--kill out the negatives by developing the positives. The mind produces thought; and yet, it tends to grow from the particular portion of its own product which you may choose to feed to it--for it not only creates thought, but also feeds upon it. So, finally, let it produce the best kind of thought for you, and then throw that back into the hopper, for it will use it to grind out more of the same kind and grow strong in so doing. That is the whole thing in a nutshell. The second phase of aura development (as above classified), however, is not likely to be familiar to the average student, for the reason that it is not known outside of advanced occult circles, and very little has been allowed to be taught regarding it. But, the very reticence regarding it is a proof of its importance, and I strongly advise my students to give to it the attention and practice that its importance merits. The practice, thereof, however, is extremely simple, and the principle of the practice, moreover, is based solely upon the facts of the relation of color and mental states, as shown in the astral auric colors, as fully explained in the preceding chapters of this book. In order to intelligently practice the development of the aura by means of flooding or charging it with the vibrations of psychic colors, it is first necessary that the student be thoroughly familiar with the scale of colors related to each set of mental states or emotional feelings. This scale and its key is found in a number of places in the preceding chapters.
