Educate your inner being in all aspects of life. Keep to the order you learned during your schooling. You did not begin all of a sudden to grasp the higher subjects; you started by learning the alphabet. The same applies to your soul. It is not good for it to strive toward exalted feats until it becomes familiar with the spiritual alphabet: humility and obedience. Let the whole of your life become a continuous prayer.
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.
