We should not trust our perceptions too much—that is something the Buddha taught. “Are you sure of your perceptions?” he asked us. I urge you to write this phrase down on a card and put it up on the wall of your room: “Are you sure of your perceptions?” There is a river of perceptions in you. You should sit down on the bank of this river and contemplate your perceptions. Most of our perceptions, the Buddha said, are false. Are you sure of your perceptions? This question is addressed to you. It is a bell of mindfulness. ~ Thich Nhat Hanh
