Chastity Pure Heart in Chinese / Japanese...

純潔 is associated with “chastity” but with the direct meaning of clean, innocent, and pure.

If you were expressing the idea of a “pure heart” in Chinese, while not literal, this would be the word you would use.

In Japanese, this word is sometimes used to express purity.

In Korean, it describes purity, chastity, virginity, and innocence (basically the same as the Chinese definition).
