It is the journey of the human soul on the Royal Highway to Light, Liberation, and Eternal Day. For many centuries those who have achieved this Wisdom, this "Great Work," have been trying to make it accessible to mankind, and to place it in such form that the ethical, scientific, and philosophical principles involved, and upon which it is based, should not again be lost. Every such effort has hitherto failed. The scientific spirit of the present age, in a very broad way, seemed to offer a new and a more advantageous opportunity; for the whole process is one of strict science. The Psychology of the present day has become involved in phenomena and automatism, and is in no sense _constructive_. It is one thing to build theories, and quite a different thing to systematize demonstrated facts, through the recognition of co-ordinate relations, and underlying law. The work is open and accessible to all who manifest real interest, an open mind, and who have the intelligence and discrimination to recognize the character of the work. It has never, in the history of man, been open in any other way, on any other terms, or to any other individuals. Those who can fill these requirements constitute to-day a larger number than have before existed at any one time, for perhaps many centuries. The "School of Natural Science" is in evidence. The "Great Work" is carefully outlined. There is no bar to one's making a beginning on the path, except indifference, incredulity, preoccupation, or prejudice; and these need not be in the least disturbed, for they will be kindly and courteously passed by. Arguments, controversy, and proselyting, have no part in the Great Work, as there is no organization, and no personal ambitions to serve. Those who speak a common language, are inspired by a common purpose, and aspire to a common and universal good, will, soon or late, find themselves associated together and co-operating. It is like a chorus of voices when an old song is started that we loved in childhood. Each takes up the strain, falls into his own part, and helps to swell the harmony, from the joy of his own heart. Those who "never did like the song," will "quietly steal away." Both Swedenborg and Emerson have sufficiently illustrated the "Law of Correspondencies," and "compensation," to reveal the basis of all harmonious human associations, whether on the earth, or on other planes of being. Hence the "Harmonics of Evolution," was the forerunner of the "Great Work." The pitiable byplay and claptrap of "Affinities" so often seen and heard nowadays, where all previous obligations are ignored, and personal responsibilities set at naught, only serve to emphasize the real law of harmony and constructive evolution, by showing what it is not. The Great Work digs to the very foundations of life, and all human associations, and reveals the Good, the True, and the Beautiful, in the building of character, and the adornment of the Temple of the Human Soul.
