Who's your guide?

Thomas Merton wrote, "The most dangerous man in the world is the contemplative who is guided by nobody. He trusts his own visions. He obeys the attraction of an interior voice but will not listen to other men. He identifies the will of God with anything that makes him feel, within his own heart, a big, warm, sweet interior glow...such a man can wreck a whole city, or even a nation" (New Seeds of Contemplation).
