In being true to the small voice within, you are being of service to others and to the world in the most profound way possible. You cannot know where that voice will take you, but in being willing "to save the only life you could save," you are affirming one of the deepest and most sobering truths of all: no one else can ever walk your journey for you. You alone can respond to your call.
I breathed a song into the air,
It fell to earth, I knew not where;
For who has sight so keen and strong,
That it can follow the flight of song--
The song from beginning to end,
I found again in the heart of a friend.
