What makes us human beings is the Five Skhandas, correct? Form, feeling, perception, fabrication, conciousness.
Form is the physical make up of you, your body. Why is it that every time I read about the five aggregates, form is mentioned first? Form would include the brain, of which today scientists and psychologists generally agree, 'generates' or 'allows' the mind, or if you prefer, 'allows the latter four aggregates'.
Take away the body, form, and the latter four aggregates cannot exist. Take away the brain, and the latter four aggregates cannot exist. When the man with a sick mind goes to a Therapist, gets medicine that affects the brain, typically his mind is healed and/or helped. Correct me if i'm wrong.
