Such sad news. I haven't been in touch with Chris in quite a few years, yet I know he continued his passionate devotion to the dharma, to practice and study, and to teaching, all with his typical verve. He embodied the dedication of the best of practitioners and enthusiastically shepherded Boston sangha in their own practice and study (and fun!).
Last night I dreamed (it must have been after some large event or other) folks were gathering their shoes from the remaining mess after most had left. We stragglers were alarmed to find out that we had missed our ride! Then Chris appeared and offered to drive us all home.
I wish him travels filled with brilliance.
