A student of the zen master Gisan attained enlightenment in one moment of waste.
When Gisan asked the student to bring a pail of water for his bath, the student poured it in and threw the remainder on the ground. The master scolded him: "Why didn't you give the rest of the water to the plants? What right have you to waste even a drop of water in this temple?"
In that instant, the student realized zen.
