Zen is basically resignation, since it does not recognize the God of Heaven and Earth.
As a Christian, when terrible things happen, I can have faith that in the overall picture, the misfortune has a place in God’s plan. I can tell you that my misfortunes have served to teach me some lessons.
In Zen Buddhism, you are working out the wrongs in your life or a previous life. There is no grace or forgiveness in Zen Buddhism. That’s why there is so much suffering in places like India. They consider it a kindness to let you work out your suffering.
That misses the point. India was always filled with suffering, which Buddha said could never be fixed, but through detachment, one could rise above it.
