  One thing bothers me in Graef's presentation: his definition of zazen as "sitting with the mind focused or toally absorbed in one thing." To me this confuses zazen/shikantaza with samatha meditation. (See my description of kinds of meditation.)
  
  But his description of relating to the world as "our universal self" rings true to me; it's what I experience. I might quibble with him a bit on the need for years of rigorous training before you can really be centered in that perception; I might put a bit more emphasis on yielding to the call of that essential nature. But in the end that's a question of effort vs realization, and as Melanie Klein observes in Meeting the Great Bliss Queen, these are necessary to each other -- two sides of the same coin. Each of us must work out our own balance between them.
