大方廣佛華嚴經隨疏演義鈔 11.34

11.34

疏「二互遍相資義」，即同體門。文中亦四：初正釋、言「則具多箇一」者，如十錢為緣，一錢當體自是本一，應二之時乃詺初一，以為二一。應三為三一，乃至應十為十一，故有多一。

In the commentary, "Second, the meaning of mutual pervasion and mutual assistance" is the gate of identical essence. Within the text there are also four: first, the direct explanation. Saying "it then possesses multiple ones": for example, with ten coins serving as conditions, one coin in its own essence is naturally the original one; when responding to the two, that first one is designated as the two-one; responding to the three, it is the three-one; and so on up to responding to the ten, it is the ten-one; hence there are multiple ones.
