The student should turn back the pages of this book, and then carefully re-read and re-study every word which has been said about the relation of mental states and auric colors. He should know the mental correspondence of the shades of red, yellow, and blue, so thoroughly that the thought of one will bring the idea of the other. He should be able to think of the corresponding group of colors, the moment he thinks of any particular mental state. He should be thoroughly familiar with the physical, mental, and spiritual effect of any of the colors, and should moreover, test himself, psychically, for the individual effects of certain colors upon himself. He should enter into this study with interest and earnestness, and then by keeping his eyes and ears open, he will perceive interesting facts concerning the subject on every side in his daily work and life. He will perceive many proofs of the principle, and will soon amass a stock of experiences illustrating each color and its corresponding mental state. He will be richly repaid for the work of such study, which, in fact, will soon grow to be more like pleasure than like work. Having mastered this phase of the subject, the student should give himself a thorough, honest, self-examination and mental analysis. He should write down a chart of his strong points and his weak ones. He should check off the traits which should be developed, and those which should be restrained. He should determine whether he needs development along physical, mental, and spiritual lines, and in what degree. Having made this chart of himself, he should then apply the principles of charging the aura with the color vibrations indicated by his self diagnosis and prescription. The last stage is quite simple, once one has acquired the general idea back of it. It consists simply in forming as clear a mental image as possible of the color or colors desired, and then projecting the vibrations into the aura by the simple effort of the will. This does not mean that one needs to clinch the fist or frown the brow, in willing. Willing, in the occult sense, may be said to consist of a COMMAND, leaving the rest to the mechanism of the will and mind. Take away the obstacle of Doubt and Fear--then the Royal Command performs the work of setting the will into operation. This, by the way, is an important occult secret, of wide application--try to master its all important significance.
