On the contrary, meditation puts us directly in touch with our innermost thought processes. The idea is to learn to let the mind be, to let thoughts arise and subside without the usual tendency to try to push and pull them. Much of the difficulty one faces in dealing with a disability stems from the constant attempt to measure up to supposed social norms. Meditation helps put things in a truer perspective. This approach contains within it the implicit assumption that the disabled person will never fully arrive.
Meditation calls into question much of what passes for normalcy.
Much better to reach an individual, unique assessment of one's strengths and weaknesses than to chase after conventional, and often unexamined, notions of happiness. The rage is extra, unnecessary, often blocking the very communication which could change the situation. Compassion is the highest good in Buddhism, turning the focus away from one's individual situation towards that of society at large. I in no way mean to minimize the social and physical problems facing the disabled, but the success stories among our group always seem to be based on a high degree of self-knowledge and an empowered attitude. Meditation is a powerful tool for doing that work.
