There are no limits on true self-giving. It is not just to those one likes that one makes the offering. This involves a love that issues from the very CENTER of the person's being, directed to the CENTER of the other person's being, a love that gives ALL that the person is in order to foster the other person's life, a love that is offered to EVERYONE, without exception and without condition. The love is not offered to people because they are one's friends; people become "friends" because one loves them.
I am one of a new breed, a hospital musician. Last week a doctor who had come out of a difficult eight-hour surgery heard the piano and stopped to rest. He said the aria I was playing from Bach's Goldenberg Variations revived him by reminding him of the larger picture. He said he felt more accepting of the outcome of the operation he'd performed. The man who'd received a new kidney said, "Beethoven's Ninth Symphony reminded me how much I want to live, how much I love life. After listening to the music I was able to pray again."
