自下第三以頌總收中，嗢柁喃曰者，嗢柁喃頌有三：一者、是初，謂辨法時初以一頌謂不重頌總列諸門後依門釋；二者、是中，即是重頌辨法未了中間舉頌重收前義；三者、是後，謂辨法竟總舉重頌頌前義。

From here below, third, in summarizing with verses, regarding 'The udāna says': there are three kinds of udāna verses: first are the initial ones, which, when analyzing dharmas, initially list all the headings with a single verse without repeating verses, after which it explains according to the headings; second are intermediate ones, which are reiterative verses that, before the analysis of dharmas is complete, are introduced in the middle to summarize the preceding meanings; third are the concluding ones, which, after the analysis of dharmas is finished, generally introduce reiterative verses to versify the preceding meanings.
