During this time period, Jobs and Brennan both became practitioners of Zen Buddhism through the Zen master Kōbun Chino Otogawa. Jobs was living in his parents' backyard toolshed, which he had converted into a bedroom. Jobs engaged in lengthy meditation retreats at the Tassajara Zen Mountain Center, the oldest Sōtō Zen monastery in the US. He considered taking up monastic residence at Eihei-ji in Japan, and maintained a lifelong appreciation for Zen, Japanese cuisine, and artists such as Hasui Kawase.
