In Mental Chemistry Charles Haanel expands on galore of the most powerful and important principles that he originally instructed in the Master Key System course. He tells us:

"Chemistry is the science which treats of the intra-atomic or the intra-molecular changes that materials things undergo under various influences. Mental is defined as "of or pertaining to the mind, including intellect, feeling, and will, or the entire rational nature."

"Science is cognition gained and verified by exact

observation and correct thinking. Mental chemistry is, therefore, the science which treats of the changes that conditions undergo through the operation of the mind"

As the transformations that are brought just about in applied chemistry

are the result of the orderly combination of materials, it follows that mental chemistry brings just about results in a like manner."
