Ultimately, if you repeatedly re-create the experience of compassion at will, practicing it independent of any circumstance in your life, your body would become the mind of compassion. You would memorize compassion so well that nothing from your outside world could move you from this state of being. Now all three brains are working together; and you are biologically, neurochemically, and genetically in a state of compassion. When compassion becomes unconditionally ordinary and familiar for you, you have progressed from knowledge to experience to wisdom.
