INTERESTING TRIVIA. “The monk Mumon (“No-gate”), in the thirteenth century, compiled forty-eight koans, following each with a commentary and a small “poem”. This work is called “The Gateless Gate” or the Mumonkan (“No-gate barrier”). It is interesting to note that the lives of Mumon and Fibonacci coincided almost exactly: Mumon living from 1183 to 1260 in China, Fibonacci from 1180 to 1250 in Italy.” (Fibonacci sequence, such that each number is the sum of the two preceding ones).
