In 1936, his earlier interest in Zen broke
through once again, and he began his Zen practice, which continued for the next
twenty-four years at Shokoku-ji, under master Yamazaki. His dual interest in
philosophy and Zen, as Heisig recounts, “was a matter, as he liked to say, of a

sitting and then thinking.’ ” The name given to him by his master was Keisei
(“voice of the valley stream”). (1743/3699)
