Bill, Anthony, I wondered if you, or others here, can recommend equipment or furniture (chairs /benches and such), that has worked well for people who can no longer, (or never have) been able to use a safu in a traditional sitting posture. For those with less flexability, or have arthritis, back /joint pain, and the rest. I am wondering if using a safu on the chair is necessary to achieve the proper zazen state, and how it affects the duration of time and frequency of the sitting practice. I suppose I'm asking about the quality of the zazen experience for them There has always so much insistence on posture. Any thoughts? Thanks, Kristy
