Sophrosyne

Sophrosyne (Ancient Greek: σωφροσύνη) is an ancient Greek concept of an ideal of excellence of character and soundness of mind, which when combined in one well-balanced individual leads to other qualities, such as temperance, moderation, prudence, purity, decorum, and self-control. An adjectival form is "sophron". It is similar to the concepts of zhōngyōng (中庸) of Chinese Confucianism and sattva (सत्त्व) of Indian thought.
