Human behavior (what a person does) changes the brain. People are born life-affirming (seeking and loving life). However, the brain, at birth, contains the “seeds” for abnormal behavior. If a person engages in life-denying activity (murder and jihad), these seeds grow larger, becoming “seedings.” As they grow larger it becomes increasingly difficult to change back to normal behavior.
The black areas in the brain (see diagrams below) are found in all human beings. These represent impulses toward abnormal behavior. The size of these areas is affected by what a person does. If one engages in life-denying activity (murder and jihad), these areas become larger.
