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.
We must pass through solitude and difficulty, isolation and silence, to find that enchanted place where we can dance our clumsy dance and sing our sorrowful song. But in that dance, and in that song, the most ancient rites of our conscience fulfill themselves in the awareness of being human.
