Vietnamese-born monk and writer Thich Nhat Hanh writes in Zen Keys (1994):

I remember a short conversation between the Buddha and a philosopher of his time.

“I have heard that Buddhism is a doctrine of enlightenment. What is your method? What do you practice every day?”

“We walk, we eat, we wash ourselves, we sit down.”

“What is so special about that? Everyone walks, eats, washes, sits down…”

“Sir, when we walk, we are aware that we are walking; when we eat, we are aware that we are eating… When others walk, eat, wash, or sit down, they are generally not aware of what they are doing.”
