Not being in — not being attached to… whoever you are — is the essence of Zen,” Mr. Glassman explains in the book.

“When we’re not attached to our identity, it allows all the messages of the world to come in and be heard. When we’re not in, creation can happen.”

Bernard Glassman, 1939-2018, Zen Master and Social Activist, book quote from The Dude and the Zen Master
