逕解為 "邪不勝正" 是牴觸原文意 是未究深意 「道高一尺，魔高一丈。」 原為佛家告誡修行者，謹防外界誘惑，因正氣難以修得，而邪氣卻容易高過正氣。 西遊記˙第五十回：「道高一尺，魔高一丈，性亂情昏錯認家。」 初刻拍案驚奇˙卷三十六：「道高一尺，魔高一丈，冤業隨身，終須還帳。」 後用以比喻一事興起，又會有一事超過其上。

erm... hehe, good question! it's like when you are being mean, but there is always a person who is MEANER than you. e.g. Gosh, I've skipped my English class this morning and i thought my teacher would never know i wasn't there. But she got us a pop quiz and took it as a roll call... glarhhhh... it's truly like 道高一尺魔高一丈!

"道高一尺魔高一丈" —————— 含贬义，两种可以分开使用 现在用来表示邪恶的事物抵不过正义的事物。 意思就是一尺的道需要一丈的魔来抵消，说明的道的强大。 后世哲学认为，道不在于形神巨细，而魔不管其强大与否，道这一尺必须压在魔这一丈之上，谓之邪不胜正也。

原意是宗教家告诫修行的人要警惕外界的诱惑。后比喻取得一定成就以后往往面临新的更大的困难。

"If you give him an inch he'll take a mile"=得寸进尺；“道高一尺魔高一丈”=While the priest climbs a post, the devil climbs ten.
