When we chant the Heart Sutra, we’re not just making a noise.
But we are making a noise. Seen from the concrete perspective, it’s just noise.
Seen from the abstract persective, it’s just meaning. But both these persectives are expressed and transcended by the simple action.
If we see zazen as a concrete act, we understand neither zazen or the concrete. If we see it abstractly, it’s lost too.
