I am reading a book by Caroline Myss, "Why people don't heal and how they can". She says that that an illness can also be an answer to a prayer, an illness can physically take us on a path of insight and learning that we would otherwise never venture on; an illness can be an initiator for the broadening of personal awareness and also for understanding the bigger picture of life.

Most of us are too lazy, too complacent to go out of our comfort zones and search for true happiness. Getting ill can be a way for the Universe to enable us to get out of that.
