People with extra physical challenges - disabilities, chronic illnesses, or advanced age - often find it impossible to participate fully in Zen practice without special accommodations. Seated meditation (zazen) can be painful, and the demands of silent meditation retreats (sesshin) can be prohibitive. However, an important part of Zen practice - especially sesshin - is how everyone follows the forms together, doing the same things at the same times. The whole idea is to minimize the need to exercise personal choice, and to use a certain amount of physical discomfort to bring us up against the existential matter of our lives. How can Sanghas support the Zen practice of people with physical challenges while preserving what is supportive to those without them?
