大方廣佛華嚴經隨疏演義鈔 48.47

48.47

疏「一如飲無間」，此即敵體相似。斷世渴愛常求佛智，即惑翻也。得法喜樂等，即順也。入海霔雨，即同水義也。下諸門中體勢亦爾，隨時解釋。

Regarding the commentary's "First, like drinking without interruption": this is exact resemblance. Severing worldly thirst and craving and constantly seeking the Buddha's wisdom reverses delusion. Attaining Dharma joy and bliss accords [with the good]. Entering the ocean and pouring down rain matches the meaning of water. In the various gates below, the essential structure is also like this, explained as the occasion arises.
