Fact: God created humans such that emotion not processed by the frontal lobe of the brain becomes stored in the body as tension.
Fact: Frontal lobe of brain is center of human awareness/consciousness. It is the part of the brain which enables conscious relationship.
Fact: Unprocessed emotion causes a deterioration in health.
Fact: Torah tradition teaches that a lack of health comes because of some lack in relationship with God.
Hypothesis: Emotions stay with us until we experience awareness of them, i.e. have relationship to them because one of the main things God wants is a relationship with us. Ideally, He wants intimacy. That is why emotion must be involved. A person disconnected from emotion becomes ill.
This would explain why Rachmana leiba bai--God wants the heart--is a basic tenet of Torah. And the service of the heart is prayer--i.e. talking to God.
Heartfelt communication is at the root of intimacy. What would it be like if a man wanted intimacy with a woman (or vice versa) and, even though she is in the room with him, all he does is talk about her, but not to her. Or let's say he talks to her, but only via a script he was given and never actually talks to her from his heart. What kind of intimacy would be engendered?
That's how many of us deal with God. We talk about Him, but not to Him--not from the heart. At best, we talk to Him via the script written two thousand years ago by the Men of the Great Assembly.
Suggestion for healing: Talking to God from the heart causes emotion to be digested because it activates the frontal lobe of the brain into the body and releases emotional tension, producing greater health and wellbeing. This is because God wants true, intimate relationship.
