Life in the widest sense is what humans experience and live for. But what is a truly human life? All life needs tending, nurturing, caring for, and human life especially requires physical, mental, moral, and spiritual care for body, mind, spirit, and soul. That means human life needs spirituality like the body needs breath and blood to flourish. …zest for life shows itself in the development of a more integrated, stronger global community that will give priority to promoting more equality, justice and peace as well as a planetary ethic. Humanity is at the crossroads; it cannot be considered simply as a state that has been reached but must be approached “as a work that has to be done.”
