Worth reading but ironically, it goes in circles, repeating itself endlessly. I feel it could have been more succinct. Here some key quotes from the book:
"Form is emptiness and emptiness is form."
"Zen practice is the direct expression of our true nature."
"When you give up, when you no longer want something, or when you do not try to do anything special, then you do something."
"When we express our true nature, we are human beings. When we do not, we do not know what we are."
"Because all of us are doing the same thing, making the same mistake, we do not realise it. So without realising it, we are making many mistakes."
"Zen activity is activity that is completely burned out, with nothing remaining but ashes."
"If you are ready to accept things as they are, you will receive them as old friends, even though you appreciate them with new feeling."
"You have difficulty because you have feeling."
"Our life and death are the same thing. When we realise this fact we have no fear of death anymore, and we have no actual difficulty in life."
"When you study Buddhism, you should have a general house cleaning of your mind. You must take everything out of your room and clean it thoroughly. If it is necessary, you may bring everything back in again. You may want many things, so one by one you can bring them back. But if they are not necessary, there is no need to keep them."
"If we are prepared for thinking, there is no need to make an effort. This is called mindfulness. Mindfulness is, at the same time, wisdom."
"In the beginner's mind there are many possibilities, but in the expert's there are few."
