In order to meet an objection which may be raised by certain people already possessed of some psychical experience, let it be at once admitted that there are shorter ways than this, and that there are persons who have direct perception of the actualities of birth and death, without having had to pass through all the stages of discipline here set forth. There are also human beings endowed with high psychical faculties, to whom only a slight impulse is necessary for the developing of these powers. But they are exceptional, and the methods described above are safer, and are capable of general application. Similarly, it is possible to gain some knowledge of chemistry by special methods; but in order to make safer the science of chemistry, the recognized, reliable course must be followed. An error fraught with serious consequences would result from the assumption that the goal could be reached more simply by allowing the mind to dwell merely on an imaginary plant or a grain of seed. It may be possible by such means to evoke a force which would enable the soul to attain the inner vision. But this vision will be, in most cases, a mere figment of the imagination, for the main object is not to create arbitrarily a mental vision, but to allow the veritable nature of things to form an image within one's mind. The truth must come up from the depth of one's own soul, not at the call of one's ordinary self, but rather must the objects of one's perception themselves exercise their magical power, if one is to perceive their inner reality. After the disciple has evolved, by such means, the rudiments of spiritual vision, he may proceed to the contemplation of human nature itself. Simple appearances of ordinary life must be chosen first. But before making any attempts in this direction, it is imperative for the student to strive after an absolute sincerity of moral character. He must banish all thoughts of ever using the insight to be attained in these ways for his own selfish ends. He must be absolutely determined that under no circumstances will he avail himself, in an evil sense, of any power which he may gain over his fellow-creatures. This is the reason why everyone who desires to gain direct insight into the secrets of human nature must follow the golden rule of true Occultism. And the golden rule is this: For every one step that you take in the pursuit of the hidden knowledge, take three steps in the perfecting of your own character. He who obeys this rule can perform such exercises as that which is now to be explained.
