金剛經纂要刊定記 1.91

1.91

望源迷派者。望謂瞻望。源謂水生之處也。迷謂昏迷。派謂流派。路分曰岐，水分曰派。意云：此經雖宗無相，而文義千差。今雖符大底宗源，而全乖差別義理，故云望源迷派已。斯言乃是曉公《起信》序文。今雖用之，而意異彼。彼則以一心為源，隨緣生滅為派。此則以經宗為源，義理為派。故不同也。

As for "gazing at the source yet bewildered by the streams": "gazing" means looking up toward; "source" means the place where the water arises. "Bewildered" means confused and darkened; "streams" means branch currents. When a road divides it is called a fork; when water divides it is called a branch stream. The meaning is: although this sūtra takes marklessness as its tenet, its textual meanings contain a thousand differences. Now, although one tallies with the general, fundamental source of the tenet, one entirely departs from the differentiated principles and meanings; hence it says "gazing at the source yet bewildered by the streams." These words are in fact from Master Wŏnhyo's preface to the Awakening of Faith. Although used here, the meaning differs from his. In his work, the One Mind is the source, and arising and ceasing in accord with conditions are the streams. Here, the sūtra's tenet is the source, and the principles and meanings are the streams. Thus they are not the same.
