Re: Zazen necessary for training
As I never get tired of repeating, I hope you realise that sipping wine used to be an established Zen (Ch'an) method in the heydays of ancient China. I practise that wise approach to meditation quite regularly on my balcony, and the myriad things become one very easily.
I dont know what cultural decline set in to eliminate that form of practice from the Zen canon....
(My reference here is David Hinton's fantastic book "Mountain Home".)
