陰陽師身おんようじみの上知うえしらず

expression

people don't know themselves as well as they know others; a fortune teller can't tell their own future

Proverb meaning that one is often blind to one's own affairs while being able to see others' clearly. The literal reading refers to an onmyōji (yin-yang master) who cannot divine their own fate.

• 「陰陽師おんようじ身みの上うえ知しらず」というように、他た人にんのことはよくわかるのに自じ分ぶんのことはわからないものだ。

  As the proverb goes, 'even an onmyōji doesn't know their own fate'—we often understand others well but not ourselves.
