expression, ichidan verb
to divine using the I Ching
Specifically refers to divination by consulting the I Ching (易経). The expression is a set phrase; 易 here means the I Ching, not 'easy'.
彼は毎朝、易を見てその日の運勢を占う。
Every morning he consults the I Ching to divine his fortune for the day.
The expression combines 易 (the I Ching) with 見る (to look at, to examine). The exact historical derivation is uncertain, but it is a conventional phrase for consulting the I Ching.
