Hello:
The problem is not the words, but the concepts the words are being used to address. The brain is incapable of perceiving the MIND or Spiritual realms within us... however, the MIND feeds the brain thoughts [I refer to these thoughts as D-Think, for Delusional Thinking], that cause us to believe that we can understand anything with our brains.

The MIND is not physical, and the brain is. To access ones MIND intentionally requires training and practice... even though we do access it automatically [and momentarily] whenever we are enraged or in deep grief....then we quickly begin thinking and the rage turns to "anger" and the grief turns to "sadness". The raw emotion is MIND-level energy, and the feelings are brain-level thinking.

Because there are very few words for the energy operations within the MIND and Spiritual realms within us, I have created terms and symbols for these operations and processes. One word we do have, such as "mind", is most often used interchangeably with brain, and thus, "mind" no longer refers specifically to the non-physical energy simultaneously existing with us.... and this is the reason I use all capital letters for MIND, simply to try and differentiate it from "mind".
