妙法蓮華經玄贊 5.66

5.66

贊曰：知佛與魔道跡不同，所以疑斷。魔說乖真所以疑起，佛語符妙由此疑滅。

The Commentary says: Knowing that the traces of the path of the Buddha and Māra are different, doubt is therefore severed. Because the speech of Māra contradicts the real, doubt arose; because the Buddha's words accord with the marvelous, doubt is thereby extinguished.
