2.81

法融云：一者向上來者，一云：此門初錢但有去義無來義，第十錢中但有來義無去義。一云：反此也。謂初錢有力將十錢來故云來，第十錢有力將十錢去故云去也。本數者，問：本一與本數何別？答：位不授時呼一，則十皆應云吾亦一。吾亦一故，授第一乃至第十等位時，以第一之一本是一故授第一位，故云本數一也。又以數十之初一，故云本一也。

Farong said: Regarding 'one being coming upwards', one explanation states: In this gate, the initial coin has only the sense of going and not the sense of coming; the tenth coin has only the sense of coming and not the sense of going. Another explanation states: It is the reverse of this. That is, the initial coin has the efficacy to bring the ten coins along, hence it is called 'coming'; the tenth coin has the efficacy to take the ten coins away, hence it is called 'going'. Regarding 'original number', Question: What is the distinction between the original one and the original number? Answer: When positions are not assigned, upon calling out 'one', then all ten would respond, 'I too am one.' Because they are 'I too am one', when assigning positions from the first up to the tenth, because the one of the first is originally one, it is assigned the first position; therefore it is called the 'original number one'. Furthermore, because it is the initial one in counting ten, it is called the 'original one'.
