Dear @Randy and @mitchellmckain
I like to use Rob Hoffman’s model for a human because of its simplicity. I think it is good foundation to start from. Hoffman defines the human as a quadrinity, made up of the intellectual self, the emotional self, the physical self (body) and the true self (soul). The goal of enlightenment is to find harmony among all four aspects of self - giving room for each aspect of self to find fulfillment.
Chemical processes take place in the body, but the question for science to help determine is: Are the chemical reactions the cause of the emotion, thought, word, movement, or a reaction to the same. The act of crying for example, can be the body’s reaction to dry conditions, or the emotional self’s reaction to loss, or the true self’s cry for attention.
