history
Used in the Jin Shu (《晋书·苻坚载记·王猛》) to describe Wang Meng, who remained 悠然自得 and unbothered when 'fashionable scholars' mocked him. The phrase captures that quiet inner ease that doesn't need external approval.
memory
悠然 = 'leisurely and far-away in mood' + 自得 = 'pleased with oneself.' Picture someone unhurried, softly smiling to themselves.
