'Erbarme dich mein got' by J.S Bach from the "matthäus passion"(or st matthew passion)
It made me cry. It helped to 'melt the ice' in my throat and heart when I was very sad.
I'm no christian, but I do have a special relationship with Jesus. And to know what happened to this man, what he has gone through, how he must have felt during that intense suffering.
Just put on the song..
(If you don't have it, i'd be more than willing to send it to you - just give me your email)
It also reminds me of how fragile we as humans can be. How small things can alter our lives and feelings so gravely. We are magnificent and great beings, but down here, we sometimes are just but shadow and dust. So fragile. So powerless.
