The seven hermetic principles, which are the foundation of spiritual knowledge and science, are as follows:
The Principle of Mentalism
"THE ALL is MIND. The Universe is Mental."
THE ALL is the reality underlying the material universe. THE ALL is spirit which is unknowable and undefinable, as an infinite, living mind. The material universe is a mental creation of THE ALL.
The Principle of Correspondence
"As above so below. As below, so above."
There are correspondences connecting all the planes of life, from the physical world to the metaphysical worlds. The Principle of Correspondence can be used to know what would normally be unknowable. An event in the physical can be used to get a glimpse of what's happening in an unseen dimension.
The Principle of Vibration
"Nothing rests. Everything moves. Everything vibrates."
A rapidly moving wheel has the illusion of being motionless. Such is the case with physical matter, which has varying rates and states of vibration. States of mind are also vibratory, and can be altered with the use of will.
The Principle of Polarity
"Everything is Dual. Everything has poles. Everything has its pair of opposites. Like and unlike are the same. Opposites are identical in nature, but different in degree. Extremes meet. All truths are but half-truths. All paradoxes may be reconciled."
With the use of will, polarity can be controlled. When there is an undesired polarity, instead of fighting the undesired polarity, the opposite and desired polarity can become the main focus.
The Principle of Rhythm
"Everything flows, out and in. Everything has its tides. All things rise and fall. The pendulum-swing manifests in everything. The measure of the swing to the right is the measure of the swing to the left. Rhythm compensates."
It's possible to stay at a particular part of the pendulum, so that when the swing goes in an undesired direction, one can avoid being dragged along with it.
The Principle of Cause and Effect
"Every cause has its effect. Every effect has its cause. Everything happens according to Law. Chance is but a name for Law not recognized. There are many planes of causation, but nothing escapes the Law."
Only causes of events within a certain range can be perceived without being overwhelmed, but causes are multi-layered and go back in time forever. When higher laws are accessed, lower laws can be commanded.
The Principle of Gender
"Gender is in everything. Everything has its masculine and feminine principles. Gender manifests on all planes."
Gender is not only sexual. Gender extends to giving and receiving on all planes. The masculine expresses, and the feminine receives and creates. The "Me" aspect of oneself is the personality, and is feminine. The "I" aspect of oneself is the will, and is masculine. One can connect to their own inner "I," instead of being controlled by the "I's" of others.

Two other very powerful books on hermeticism are "The Secret Science for the Spiritual Transformation of Man (Hermetic Philosophy, book 1)," and "The Stellar Man." Both are written by by John Baines.
By absorbing these three books and applying their knowledge to life, self-empowerment is the result, which can have a ripple effect for planetary liberation.
Also, for those who are interested in Ets, John Baines states that the original founders of Rosicrucianism are extraterrestrial.
