華嚴法界玄鏡 2.20

2.20

觀曰：七、真理即事門，謂凡是真理必非事外，以是法無我理故，事必依理，理虛無體故。是故此理舉體皆事，方為真理。如水即波，無動而非濕，故即水是波。思之。

The Contemplation says: Seven, the gate of true principle being identical to phenomena. This means that whatever is true principle is never outside phenomena, because it is the principle of the selflessness of dharmas, phenomena must rely on principle, and principle is empty and devoid of [independent] essence. Therefore, only when this principle in its entirety is completely phenomena is it true principle. It is like water being identical to waves: there is no movement that is not wetness, and thus water itself is waves. Reflect on this.
