Your breath should be light, even and flowing, like a stream of water running through the sand. Your breath should be very quiet, so quiet that a person sitting next to you cannot hear it. Your breathing should flow gracefully, like a river, like a water snake crossing the water, and not like a chain of rugged mountains or the gallop of a horse. To master our breath is to be in control of our bodies and minds. Each time we find ourselves depressed and find it difficult to gain control of ourselves by different means, the method of watching the breath should always be used.
