With the commencement of the twentieth century a further step was taken. It was realized that something must be done to make religion scientific as well as to make science religious, in order that they may ultimately blend; for at the present time heart and intellect are divorced. The heart instinctively feels the truth of religious teachings concerning such wonderful mysteries as the Immaculate Conception (the Mystic Birth), the Crucifixion (the Mystic Death), the cleansing blood, the atonement, and other doctrines of the Church, which the intellect refuses to believe, as they are incapable of demonstration, and seemingly at war with natural law. Material advancement may be furthered when intellect is dominant and the longings of the heart unsatisfied, but soul growth will be retarded until the heart also receives satisfaction. In order to give the world a teaching so blended that it will satisfy both the mind and heart, a messenger must be found and instructed. Certain unusual qualifications were necessary, and the first one chosen failed to pass a certain test after several years had been spent to prepare him for the work to be done. It is well said that there is a time to sow, and a time to reap, and that there are certain times for all the works of life, and in accordance with this law of periodicity each impulse in spiritual uplift must also be undertaken at an appropriate time to be successful. The first and sixth decades of each century are particularly propitious to commence the promulgation of new spiritual teachings. Therefore the Rosicrucians were much concerned at this failure, for only five years were left of the first decade of the twentieth century. Their second choice of a messenger fell upon the present writer, though he knew it not at the time, and by shaping circumstances about him they made it possible for him to begin a period of preparation for the work they desired him to do. Three years later, when he had gone to Germany, also because of circumstances shaped by the invisible Brotherhood, and was on the verge of despair at the discovery that the light which was the object of his quest, was only a jack-o-lantern, the Brothers of the Rosicrucian Order applied the test to see whether he would be a faithful messenger and give the teachings they desired to entrust to him, to the world. And when he had passed the trial they gave him the monumental solution of the problem of existence first published in “_The Rosicrucian Cosmo Conception_” in November, 1909, more than a year before the expiration of the first decade of the twentieth century. This book marked a new era in so-called “occult” literature, and the many editions which have since been published, as well as the thousands of letters which continue to come to the author, are speaking testimonies to the fact that people are finding in this teaching a satisfaction they have long sought elsewhere in vain.
