‘The Heart Sutra says, “Form is emptiness and emptiness is form.” Logically, form is not empty and emptiness has no form, so emptiness and form negate each other. Yet the Heart Sutra says they are one and the same. Usually our rational mind does not accept this kind of twist. We say it’s contradictory and doesn’t make any sense. Allowing such a question is the beginning of Buddhist study.’ (The Mountains and Waters Sutra)
Reading this book ahead of my class on getting to grips with Dogen, this last line was the one that turned a key inside me when I read it.
