From the back cover of, Two Zen Classics: The Gateless Gate (Mumonkan) and The Blue Cliff Records (Hekiganroku):
“Katsuki Sekida (1893–1987) was by profession a high school teacher of English until his retirement in 1945. Zen, nevertheless, was his lifelong preoccupation.”
Similarly, my work these days involves computer programming, and my preoccupation is Zen and meditation. Unless you’re willing to go live in a monastery, we all have to work to pay the bills, but that doesn’t mean we can’t practice.
