“Zen … does not confuse spirituality with thinking about God while one is peeling potatoes. Zen spirituality is just to peel the potatoes.”

The Paris Review interview (1982)
Context: My Zen master, because I’ve studied Zen for a long time, told me that every one (and all the stories weren’t written then) of the Mary Poppins stories is in essence a Zen story. And someone else, who is a bit of a Don Juan, told me that every one of the stories is a moment of tremendous sexual passion, because it begins with such tension and then it is reconciled and resolved in a way that is gloriously sensual. … A great friend of mine at the beginning of our friendship (he was himself a poet) said to me very defiantly, “I have to tell you that I loathe children’s books.” And I said to him, “Well, won’t you just read this just for my sake?” And he said grumpily, “Oh, very well, send it to me.” I did, and I got a letter back saying: “Why didn’t you tell me? Mary Poppins with her cool green core of sex has me enthralled forever.”
