Just Enough
Ōryōki is a mindful form of eating that involves the carefully choreographed use of nested bowls, a spoon, chopsticks, a bowl cleaning scraper, and a cloth for tying the whole set together. Basic objective is to pay close attention to what you are eating (in silence), finish completely all of your food, and then rinse out your bowl when you're done. The practice originated in Japan and is used for formal meals in many Zen temples in the U.S.
The three Japanese characters comprising the word ōryōki (応 ō,量 ryō, and 器 ki) translate to "just enough". Careful attention, no waste.
