心如止水无波无痕
[xīn rú zhĭ shuĭ wú bō wú hén]
Translated to 'Heart Like Still Water Without Waves Or Traces'. This suggests inner peace and stability. Just like undisturbed water that neither flows nor carries marks left, it denotes the ability to remain calm even when surrounded by tumult, reflecting tranquility, non-reactivity, and depth.
