Each of us has an innate goodness.  And many of us have made great effort to develop it.  But we may not be in touch with the truth of our goodness.  As Peter explains, the Buddha asks that we reflect on the truth of our goodness.  This essential reflection bring about joy.  And it leads us toward the development of concentration and insight.  In the talk, Peter describes the skills we learn in an effort to be in touch with our goodness.
