內心平靜 is a Chinese and Japanese phrase that is a direct translation of the western idea of inner peace.

The first two characters contain the idea of “heart,” “innermost being,” or “deep in the/your inner mind.”

The last two characters mean “tranquil” and “serene.”

I have seen this phrase used as “inner peace” for art prints and even on the side of coffee cups. But I think the translation is too literal. It feels like a direct translation from English rather than a nicely composed Chinese or Japanese phrase. See my other entries for “inner peace.”
