The best way for me to honor his passing, I felt, was to do some reading and self education about Gudo Wafu Nishijima. It did not, however, seem appropriate to ask this question in the ceremony thread. Master Gudo seems to place a good deal of empahsis on understanding Dogen in terms of translating his explanations of Zazen into the stablization of the autonomic nervous system. I believe Jundo has said that he is cautious of this understanding or has moved away from it. ( correct me if I am wrong) How then, could we better understand this conceptually?
