Do you serve a customer to make money? Or do you serve a customer to serve a customer? Do you wash dishes to get them clean? Or do you wash the dishes to wash the dishes?
Here's a story from Buddhist Monk, Thich Nhat Hanh, about 'washing the dishes to wash the dishes' and the difference between mindful and mindless:
"In the United States, I have a close friend named Jim Forest... Last winter, Jim came to visit. I usually wash the dishes after we've finished the evening meal, before sitting down and drinking tea with everyone else.
One night, Jim asked if he might do the dishes. I said, "Go ahead, but if you wash the dishes you must know the way to wash them." Jim replied, "Come on, you think I don't know how to wash the dishes?" I answered, "There are two ways to wash the dishes. The first is to wash the dishes in order to have clean dishes and the second is to wash the dishes in order to wash the dishes."
Jim was delighted and said, "I choose the second way-to wash the dishes to wash the dishes." From then on, Jim knew how to wash the dishes. I transferred the "responsibility" to him for an entire week. If while washing dishes, we think only of the cup of tea that awaits us, thus hurrying to get the dishes out of the way as if they were a nuisance, then we are not "washing the dishes to wash the dishes."
