That is Buddha’s big mind that includes everything. The mind we have when we practice zazen is the great mind: We don’t try to see anything; we stop conceptual thinking; we stop emotional activity; we just sit. Whatever happens to us, we are not bothered. We just sit. It is like something happening in the great sky. Whatever kind of bird flies through it, the sky doesn’t care. That is the mind transmitted from Buddha to us.
~ Shunryu Suzuki-Roshi
