A Mind As Wide as the Sky

A Zen talk by by Sensei Wendy Egyoku Nakao:

"The Chinese character for emptiness is ku, or sky. Our original nature is like sky—vast, unhindered, and boundless. The clouds, the birds flying, the thunder showers—have you ever seen these stick to the sky? How about the sky taking hold of a bird in mid-flight? What is binding us, setting up walls in the sky where there cannot be any?"
