The Teaching
This Principle embodies the truth that "All is Mind." It explains that The All - the Substantial Reality underlying all manifestations we know as "The Material Universe," "Life," "Matter," and "Energy" - is Spirit, which in itself is unknowable and undefinable, but may be thought of as a Universal, Infinite, Living Mind.
All the phenomenal world or universe is simply a Mental Creation of The All, subject to the Laws of Created Things. The universe, as a whole and in its parts, has its existence in the Mind of The All, in which Mind we "live and move and have our being."
Practical Application
By establishing the Mental Nature of the Universe, this principle explains all mental and psychic phenomena that occupy public attention. An understanding of this great Hermetic Principle enables the individual to readily grasp the laws of the Mental Universe, and to apply them to well-being and advancement.
The Hermetic Student is enabled to apply intelligently the great Mental Laws, instead of using them in a haphazard manner. With the Master-Key in possession, one may unlock the many doors of the mental and psychic temple of knowledge.
The Master's Wisdom
"He who grasps the truth of the Mental Nature of the Universe is well advanced on The Path to Mastery." Without this Master-Key, Mastery is impossible, and the student knocks in vain at the many doors of The Temple.
This Principle explains the true nature of "Energy," "Power," and "Matter," and why and how all these are subordinate to the Mastery of Mind. The Universe being wholly mental, it follows that it may be ruled only by Mentality.
