大方廣佛華嚴經隨疏演義鈔 89.18

89.18

Regarding the commentary's "Sixteen: the syllable sa (pronounced su + wo)": it only has an explanation of the meaning, which fully states: "because awakening to the equality of time among all phenomena cannot be apprehended." Therefore the Dazhidulun says: "Hearing the syllable sa, one knows that all aspects of all phenomena cannot be apprehended, because here sarva means all." Explanation: The treatise speaks of the knowledge of all aspects (sarvākārajñatā); hence the Lalitavistara says: "The word 'knowledge' issues the sound of indestructible wisdom." The Vajraśekhara says: "The truth of all phenomena cannot be apprehended." The Mahāparinirvāṇa-sūtra says: "Sa means expounding the true Dharma for sentient beings." The intention is to clarify that the knowledge of all aspects, expounded in accordance with the occasion, also cannot be apprehended. Therefore the present sūtra names it "pouring down great rain."
