The Koan of Effort in Practice - Domyo

Why are we intensifying our practice during Ango?  In Zen, the question of effort vs. non-effort in practice is, in itself, a Koan. Should we aim for vow, intention, motivation, with the urgency of "putting out a fire on your head"? Or, would we be better off settling into equanimity and radical acceptance, just "resting in the Samadhi of all the Buddhas"? Domyo takes input from Sangha on the positives and negatives of each approach, and further discussion follows.
