“Form is emptiness, emptiness is form,” says the Heart Sutra.
The Heart Sutra says, “Form is no other than emptiness, emptiness no other than form. There are no walls in the mind.” We are the world unfolding.
The Heart Sutra in the context of its relationship to koans and what koans are. I want to pursue that line a little bit. And the first thing to say about – probably the first attitude people have to koans is that they are a sort of tool, a gadget of some kind, and you use them and you concentrate on them, and you use them – a can opener for the mind
The Heart Sutra, like any koan, contains the universe, and so you have to go in somewhere. I want to go in through the “Mantra of Great Magic.” Even the word “mantra” is, in a certain way, a reference to magic, a sort of portable access to reality that you can carry around with you. And the word “magic” is also used for the word “mantra,” so where we use “mantra” to produce magic, there’s a transformative quality about the mantra so that, when you repeat it, when you keep company with it, you end up in its world.
