lock the many doors leading into the parts of the Temple of Knowledge which he may wish to explore. We feel that in this consideration of the teachings of The Kybalion, one may find an explanation which will serve to clear away many perplexing difficulties—a key that will unlock many doors. What is the use of going into detail regarding all of the many features of psychic phenomena and mental science, provided we place in the hands of the student the means whereby he may acquaint himself fully regarding any phase of the subject which may interest him. With the aid of The Kybalion one may go through any occult library anew, the old Light from Egypt illuminating many dark pages, and obscure subjects. That is the purpose of this book. We do not come expounding a new philosophy, but rather furnishing the outlines of a great world-old teaching which will make clear the teachings of others—which will serve as a Great Reconciler of differing theories, and opposing doctrines.
