"You can recognize a Warrior of the Light by the look in his eye. Warriors of the Light are in the world, they form part of the world, and they were sent into the world without saddlebags or sandals. They are often cowardly. They do not always act correctly. Warriors of the Light are wounded by the most foolish things, they worry about trivialities, they believe themselves incapable of growing. Warriors of the Light sometimes believe themselves unworthy of any blessing or miracle. Warriors of the Light often ask themselves what they are doing here. Often they find their lives meaningless. That is why they are Warriors of the Light. Because they fail. Because they ask questions. Because they keep looking for a meaning. And, in the end, they will find it."
(Paulo Coelho. Warrior Of The Light)
