If every person can donate their organs like eye etc. does blindness will decrease: If yes, why nobody think

Blindness or any disease is due to karma generally coming from a previous life. So if ones bad karma ends then their disease or blindness will go away in one way or another. We can not cure diseases by donating organs. We cure diseases by not sinning. But we have to surrender to our maker Also known as Krishna, Allah, Jehovah, Vishnu, etc. If one donates their organs then in their next life that person will owe them (what goes around comes around) It is the law of nature. The best thing is to end all Karma all together and get out of these material bodies. for more info on karma, reincarnation, and returning to our original eternal,spiritual body, go to harekrishnatemple.c.Read Bhagavad Gita as it is By Bhaktivedanta Prabhupada
