Kokusekiryusui (刻石流水) means "to engrave kindness received on a stone in your heart, no matter how small, and to let go of the kindness you have given like flowing water." It means not only to repay the kindness you have received from someone, but also to extend that kindness to more people. And to forget the kindness you have given the moment you give it. Originally, this phrase comes from the Buddhist scripture "Kenjo Ryusui, Juon Kokuseki (To cast your feelings away like water, and to engrave the kindness you receive on stone)," which is quite profound. The above is from a word explanation article. ↑ I went temple-hopping before, and I was deeply moved by the various instructive signs I saw at the temple, so I wrote this.
