the negative and the positive polarities are faces of the same coin, are both part of the underlying pain that is inseparable from the mind-identified egoic state of consciousness. There are two levels to your pain: the pain that you create now, and the pain from the past that still lives on in your mind and body. Ceasing to create pain in the present and dissolving past pain—this is what I want to talk about now.
