Teach her the art of inner-body awareness. Demonstrate to her the meaning of presence. As soon as she is able to access the power of the Now, and thereby break through her conditioned past, she will have a choice. Nobody chooses dysfunction, conflict, pain. Nobody chooses insanity. They happen because there is not enough presence in you to dissolve the past, not enough light to dispel the darkness. You are not fully here. You have not quite woken up yet. In the meantime, the conditioned mind is running your life.
