The Walking Discourse
Monks, there are these five benefits of walking meditation. Which five?
Endurance for long journeys: One becomes capable of enduring long-distance walking.
Endurance for striving: One becomes capable of enduring spiritual exertion and effort.
Good health: One experiences little illness and disease.
Good digestion: What is eaten, drunk, chewed, and tasted is properly digested.
Long-lasting concentration: The concentration gained through walking meditation lasts for a long time. (It remains for a long time.Indeed, the sign (nimitta) acquired by one standing up is lost when sitting down, and the sign acquired by one sitting down is lost when lying down. But the sign acquired while moving and determined on walking meditation is not lost whether one is standing, sitting, or lying down.)
These, monks, are the five benefits of walking meditation.
