大乘義章 1.74

1.74

第三假中，諸法非一，其中長短大小高下，彼此往來貴賤好惡，如是一切皆是相待。如一丈物不對五尺，長相不生、長名不起；由對五尺，長相始分、長名得起，名相待假，如是一切。第四假中，法亦非一，但令諸法從前起後次第相接，皆名相續。

In the third provisionality, dharmas are not of one kind; among them, long and short, large and small, high and low, that and this, coming and going, noble and base, good and bad—all such [relations] are mutually dependent (相待). For instance, if an object of one zhang is not contrasted with five chi, the characteristic of 'long' does not arise, nor does the name 'long' occur; due to being contrasted with five chi, the characteristic of 'long' is first distinguished and the name 'long' can arise—this is called provisionality of mutual dependence; all are like this. In the fourth provisionality, dharmas are also not of one kind; as long as dharmas arise from the former to the latter, contiguous in sequence, they are all called continuity (相續).
