Quotes

 * "The lips of wisdom are closed, except to the ears of Understanding."

 * "Mind (as well as metals and elements) may be transmuted, from state to state; degree to degree; condition to condition; pole to pole; vibration to vibration. True Hermetic Transmutation is a Mental Art."

 * Chapter 5: The Mental Universe


 * "The half-wise, recognizing the comparative unreality of the Universe, imagine that they may defy its Laws—such are vain and presumptuous fools, and they are broken against the rocks and torn asunder by the elements by reason of their folly. The truly wise, knowing the nature of the Universe, use Law against laws; the higher against the lower; and by the Art of Alchemy transmute that which is undesirable into that which is worthy, and thus triumph. Mastery consists not in abnormal dreams, visions and fantastic imaginings or living, but in using the higher forces against the lower—escaping the pains of the lower planes by vibrating on the higher. Transmutation, not presumptuous denial, is the weapon of the Master."
 * Chapter 6: The Divine Paradox


 * "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."
