QUESTION (resumed) :
You cannot explain zazen.
QUESTION (original) :
I have always read and heard that zazen cannot be explained but practice, while you give so many explanations why?
ANSWER :
The zazen which you practice depends a great deal of the knowledge you have of the true nature of yourself and of all the things. Zazen is a pure miracle it's true, but it also depends on the state of mind in which you practise it.
KOSEN!
