“The word courage is very interesting. It comes from a Latin root cor, which means “heart.” So to be courageous means to live with the heart. And weaklings, only weaklings, live with the head; afraid, they create a security of logic around themselves. Fearful, they close every window and door—with theology, concepts, words, theories—and inside those closed doors and windows, they hide. The way of the heart is the way of courage. It is to live in insecurity; it is to live in love, and trust; it is to move in the unknown. It is leaving the past and allowing the future to be. Courage is to move on dangerous paths. Life is dangerous, and only cowards can avoid the danger—but then, they are already dead. A person who is alive, really alive, vitally alive, will always move into the unknown. There is danger there, but he will take the risk. The heart is always ready to the the risk, the heart is a gambler.
