I initially started this thread because I felt that Eckhart Tolle's way of explaining part of our suffering which he calls "the pain-body" was very helpful and I wondered if anyone else had read or heard his explanation.
Very briefly he describes an energy field in our bodies which is the remnants of pain left behind by every strong emotion that is not fully faced, accepted and then let go of. This usually begins in childhood but also continues into adolescence and adulthood. He calls it the false sense of self which is the basis of our life and can cause not only ourselves to suffer but those around us, mostly our nearest and dearest.
It thrives on negative thinking and drama in relationships, and when it arises it wants to make others miserable in order to feed on their negative reactions, and of course awakens their own pain-body. ( Many rows within marriage can testify to this.)
Hopefully for those of us who sit zazen we can learn to open the hand of thought and let the negative thoughts dissipate before real harm is done.
