Most of the memories I have of Suzuki Roshi are images - standing on the bridge, him so small and lifting rocks in the creek.
When I first came, he was going around in the zendo with his stick. He bowed behind me. I put up my hood so he could get to my shoulders. He said in a strong voice, "Take this off!" - meaning the hood attached to the scapular - and he whacked me. The next day he said to me, "Oh, I didn't know this was your kesa" and laughed. "I thought you Christians had to protect your head."
Another time he called me in and asked, "Why did you come here?" And he said, "I want to come to your monastery for three days." We met at Chester Carlson's funeral [ 1968]. It was just two miles away. He almost came but he didn't.
He said that faith and doubt belong together, that doubt is good as long as faith is the nose on the head of doubt.
In 1967 at Tassajara I asked David if he believed in a personal god and he said he could see god including the personal. He talked about his monastery, Mt. Savior, in Elimira, New York. Said his teacher there told the monks to "fall into heaven." He said from his experience there he'd advise us at Tassajara to avoid having animals or businesses. Both took too much time and energy. He said they were baking bread and making other items to sell and monks were driving around in trucks making deliveries and got so involved it became their focus.
The Summer 1983 Wind Bell quotes David as saying that monastic life is "a time not your own time."

Georget Gayuski refers to Brother David in the Fall 2000/winter 2001 Windbell article writing "Brother David correlated gracewith belongingness and sin with alienation. He suggested that realization requires a sense of belongingness, that it is the ground on which realization takes place."
