If a man carries out the culture of his thoughts and feelings and emotions in the way already described in the chapters on Probation, Enlightenment, and Initiation, he then effects a change in his soul such as Nature has effected in his body. Before this training, soul and spirit are undifferentiated masses. In such a state the clairvoyant will perceive them as interlacing clouds, rotating spirally, and having usually a dull glimmer of reddish or reddish-brown color, or, perhaps, of reddish-yellow; but after this growth they begin to assume a brilliant yellowish-green or yellow-blue hue, and become of a regular structure. A man attains such regularity of structure, and at the same time the higher knowledge, when he brings into the realm of his thoughts, feelings and emotions, an order, such as Nature has brought into his bodily organs, by means of which he can see, hear, digest, breathe, speak and so forth. Gradually the student learns, as it were, to breathe, to see with the soul, and to speak and hear with the spirit. In the following pages a few of the practical points pertaining to the higher education of the soul and spirit will be more fully treated. They are such as may be practically attained by anyone without additional instruction, and by means of which a further step in occult science may be taken. A particular kind of discipline must be patiently attempted such as to avoid every emotion of impatience, for it produces a paralyzing, yea, even a deadening, effect on the higher faculties within us. One must not expect immeasurable glimpses of the higher worlds to open out before one from day to day, for assuredly, as a rule, this does not occur. Contentment with the smallest progress, repose and tranquility must more and more possess the soul. It is conceivable, of course, that the learner may impatiently expect results, but he will attain nothing so long as he fails to master this impatience. Nor is it of any use to struggle against this impatience in the ordinary way, for then it will only become stronger than ever. It is thus that men deceive themselves, for in such a case it embeds itself all the more firmly in the depths of the soul. It is only by repeatedly surrendering oneself to a single definite thought, and by making it absolutely one's own, that anything is really attained. One should think: "I must certainly do everything possible for the culture of soul and spirit, but I will work tranquilly until, by higher powers, I shall be found worthy of definite illumination." When this thought has become so powerful in a man that it is an actual trait in his character, he is treading the right path. This trait will then express itself even in external affairs. The gaze of the eye becomes tranquil; the movements of the body become sure; the resolutions defined; and all that we call nervous susceptibility gradually disappears. Rules that seem trifling and insignificant must be taken into account.
