An old Japanese Zen master came to Cambridge University in England in the early 1970's, in the early days of Zen in the West. His name was Sasaki or Suzuki. Cambridge University is very formal. You have to get on the floor. You have to take off pants.
Nothing is that simple.
The light is within the dark, and vice versa. Things are not as black and white as they might sometimes seem. I read that you can't be altruistic until you stop wanting. That sounds impossible. You've been reading those dry old translated Buddhist books again.
