OUCH! that's a big one. we each have our own purpose to figure out. I once spoke with a dear friend who had lost 2 kids shortly after birth from a congenital disease and we spoke about the purpose of life for us was being able to live each day with love in our hearts and reach out to others instead of becoming bitter and full of pity. That's what we discussed, we are all different. For me I know that part of my purpose is to love. That may sound lame but the love of one person in my history changed my life and so it goes. It's like the movie pay it forward.

These are just my thoughts, others have other thoughts. I also wanted to say that first of all we need to accept the basic principle that life is suffering. There is no way around it. But we can learn to be with it and be witness as well as friend and the one who screams in pain. All of these things are in each of us.
