Although Alchemy is seen as pseudoscience, the Hermetic teachers expanded its meaning beyond the physical.
Mental Alchemy & Transmutation, also called a form of Mystic Psychology, is the changing of one’s mental state into a more desirable state.
The process of transmutation is not changing one state to an entirely different state but increasing or decreasing vibrational mental energy.
Hermetic Philosophy tells us that all phenomena, on all Plane of Existence (Physical, Mental, and Spiritual), are composed of equal and opposite parts (good, bad, hot, cold etc.)
The only thing differentiating each part is vibrational energy.
For example, there is no such thing as cold or hot, just a varying degree of heat energy (vibration).
All such things seem to be two parts while also being on the same infinite spectrum of vibration.
Additionally, all existence is constantly moving between the two extremes (poles).
This contains the Universal Laws of Polarity, Vibration, and Rhythm.
The key to practicing Mental Transmutation is using your awareness to understand where the root of the emotion/thought is arising from.
The second step is to polarize your mind to the opposite state.
This of course is easier said than done but by being aware of our mental vibration, we have more control over how it will manifest.
We can use our most trivial moments to propel us forward, recovering into an even more balanced state.
