By the time, in a long time I suspect, i am recognized as a saint by society, we will say I chose to be reborn sick to experience injustices and understand suffering of my fellow humans and animals better. What does chosing means in this case? Some believe Buddhas can choose their reborth at will. i am not of this view about myself. But what I do see in my life, is accepting gladly the obstacles by the end, because it was God's will for and in my life. I have felt like I could control my future kammas in this lifetime a few times through visions. Tricks of the mind no doubt, but fun and very deep meditation.
I have met many holy men, non christian, talking the most beautifully about Jesus I ever heard. india is the cradle of humanity for goodness in spirituality according to me. They have such long traditions of philosophy that their intrepretation of christianity , by the saddhus, is often the best I ever heard of Jesus and us.
