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. CHAPTER XV HERMETIC AXIOMS "The possession of Knowledge, unless accompanied by a manifestation and expression in Action, is like the hoarding of precious metals-a vain and foolish thing. Knowledge, like wealth, is intended for Use. The Law of Use is Universal, and he who violates it suffers by reason of his conflict with natural forces."--The Kybalion. The Hermetic Teachings, while always having been kept securely locked up in the minds of the fortunate possessors thereof, for reasons which we have already stated, were never intended to be merely stored away and secreted. The Law of Use is dwelt upon in the Teachings, as you may see by reference to the above quotation from The Kybalion, which states it forcibly. Knowledge without Use and Expression is a vain thing, bringing no good to its possessor, or to the race. Beware of Mental Miserliness, and express into Action that which you have learned. Study the Axioms and Aphorisms, but practice them also. We give below some of the more important Hermetic Axioms, from The Kybalion, with a few comments added to each. Make these your own, and practice and use them, for they are not really your own until you have Used them. "To change your mood or mental state--change your vibration."--The Kybalion. One may change his mental vibrations by an effort of Will, in the direction of deliberately fixing the Attention upon a more desirable state. Will directs the Attention, and Attention changes the Vibration. Cultivate the Art of Attention, by means of the Will, and you have solved the secret of the Mastery of Moods and Mental States. "To destroy an undesirable rate of mental vibration, put into operation the principle of Polarity and concentrate upon the opposite pole to that which you desire to suppress. Kill out the undesirable by changing its polarity."--The Kybalion.
