華嚴經探玄記 1.61

第六理事無礙門者，亦有二義：一謂一切教法舉體真如，不礙事相歷然差別；二真如舉體為一切法，不礙一味湛然平等。前即如波即水，不礙動相，後即如水即波，不失濕體。當知此中道理亦爾，是故理事混融無礙，唯一無住不二法門，《維摩經》中盛顯斯義。又此經云「知非有是有、有是非有，非相是相、相是非相。」良由本以非有為有，是故此有即是非有。聖教准此理事無礙，思之可見。

Sixth, the gate of the non-obstruction of principle and phenomena also has two meanings: first, that all teaching dharmas in their entire essence are suchness, without obstructing the distinct differences of phenomenal marks; second, that suchness in its entire essence constitutes all dharmas, without obstructing the serene equality of the single flavor. The former is like the waves being identical to water without obstructing the marks of motion; the latter is like the water being identical to waves without losing its wet essence. One should know that the principle here is also like this; therefore principle and phenomena blend without obstruction, being solely the single, non-abiding, non-dual dharma gate; the *Vimalakīrti Sūtra* extensively reveals this meaning. Furthermore, this sūtra states: "Knowing that non-existence is existence, existence is non-existence; non-mark is mark, mark is non-mark." This is precisely because existence fundamentally takes non-existence as its being; therefore this existence is identical to non-existence. The noble teaching conforms to this non-obstruction of principle and phenomena; contemplating it, this can be seen.
