This practice must be often repeated until the candidate attains absolute poise and assurance. These trials are also dependent upon a quality which is produced by his experiences in the higher worlds. The candidate cultivates this quality to an extent which he could not possibly reach in so short a time while developing in the ordinary way, but could attain only after many incarnations. In order to bring about the change here mentioned, the following condition is necessary: The candidate must be guided altogether by what has been proven to him by the cultivation of his higher faculties, by the results of his reading in the secret symbols. Should he, during these experiences, attempt to introduce any of his own opinions or desires, or should he diverge for one moment from the laws and rules which he has proved to be right, something quite other than that which is expected will occur. In such cases the candidate loses sight of the goal for which these matters are undertaken, and the result is confusion. He has, therefore, manifold opportunities, during these trials, for the development of self-control, and this, indeed, is the principal quality needed. These trials are, therefore, much more easily endured by those who, before initiation, have gone through a life which has enabled them to acquire command of themselves. Those who have developed the characteristic of following their higher principles and ideals without thought of personal honor or desire, who always discern the duty to be fulfilled, even though the inclinations and sympathies are too often ready to lead them another way, are already unconscious initiates in the midst of every day life. They need but little to enable them to succeed in the prescribed trials. Indeed, one may say that a certain measure of initiation, thus unconsciously acquired in life, will be absolutely necessary before entering upon the second trial. For even as many who during youth have not learned to write or spell, find much difficulty in learning to do so in later years, so is it also difficult to develop, merely from a knowledge of the higher worlds, the necessary degree of self-control, if one has not already acquired a certain measure of it in the course of ordinary life. The things of the physical world do not alter by merely desiring them to do so, but in the higher worlds our wishes, inclinations and desires are causes that produce effects. If we wish to bring about particular changes in these worlds, we must hold ourselves in absolute control, we must follow the right principle, must entirely subdue the personal will.
