Is it controversial these days to talk about people who are reborn into disabled bodies as a result of their Karma? I listened to a talk by Ajahn Sumedho who wouldn't be drawn into this debate, claiming that it is speculative and not worth thinking about, but I have read Buddhist texts which claim that if one has bad karma they could be reborn into a disabled body.
For the record I work with disabled people for a living, who would be more than offended if you mentioned this to them. Not only that, but many disabled people I know have purer minds than so called abled people, and many of them are very happy in their lives despite their physical limitations.
"The original heart/mind shines like pure, clear water with the sweetest taste. But if the heart is pure, is our practice over? No, we must not cling even to this purity. We must go beyond all duality, all concepts, all bad, all good, all pure, all impure. We must go beyond self and nonself, beyond birth and death. When we see with the eye of wisdom, we know that the true Buddha is timeless, unborn, unrelated to any body, any history, any image. Buddha is the ground of all being, the realization of the truth of the unmoving mind.” Ajahn Chah
