When I met Sensei he asked me “what is effort?”. rejected my answer: “no, it’s sweat!” He’d written One Inch Buddha: commentary on Hashimoto Roshi’s commentary on Dogen’s Right Effort essay. Years later he told me “Khanti paramam tapo titikkha” patience/perseverance/persistence is the greatest paramita/virtue. 10 paramitas. Meditation: calm yourself > center yourself > unify yourself. That’s more than just knowing yourself (observe and learn), it’s an active transformation. It requires persistence. All will grow in time.
