"There is such a thing as old emotional pain living inside you. It is an accumulation of painful life experience that was not fully faced and accepted in the moment it arose. It leaves behind an energy form of emotional pain. It comes together with other energy forms from other instances, and so after some years you have a "painbody," an energy entity consisting of old emotion." . . . .
