If a Buddhist practitioner is well-versed in Dharma but still behaves like an ordinary person when faced with worries and lets anger get the better of them when matters arise, then it indicates that they have not been cultivating well.
一个学佛人，如果佛法的道理都懂，但是碰到烦恼依然显现凡夫相，碰到麻烦瞋心马上出来，这就是没修好。
– Master Jun Hong Lu, Words of Wisdom Volume 5
