what you think, is
Breathing in. . .you become aware of the sensations of your body, and of your most distracting organ, your mind. Breathing out. . .you experience a release of body tension, and you struggle to bring your wandering mind back to your breath. In. . .the air tickles the tip of your nose. Out. . .the pain in your knee subsides, the mind still meanders. In. . .Shouldn't I be doing something more useful with this time? Out. . .Who's the "I" in that last thought? With ever more subtlety, eventually you come to understand, sometimes painfully, sometimes joyfully, what the Buddha realized. "We are what we think," he said.
