大般涅槃經義記 5.54

5.54

自下第八約諦辯觀，先觀苦諦，於中初先廣辯八苦，後約明觀。前中，初言生者，出相總顯生義，下別顯之，先舉後列。言「初出」者，識支是其一報之始，故名為初，報起名生。言「至終」者，名色望前說以為終。言「增長」者，即前名色增為六入。此三胎內，出胎可知。言「種類」者，出胎已後乃至老死，一報之中運運新起皆名為生。

From here below, the eighth section discerns contemplation with respect to the truths. First, the truth of suffering is contemplated, within which the eight sufferings are first extensively discerned, and then contemplation is explained accordingly. In the former, the initial word "birth" presents the mark of emergence to generally reveal the meaning of birth; below, it is individually revealed, first raised and then listed. "Initial emergence" refers to the consciousness link as the beginning of a single retribution, hence called initial; the arising of retribution is called birth. "Reaching the end" refers to name-and-form described as the end in comparison to the former. "Growth" refers to the former name-and-form growing into the six sense bases. These three are inside the womb; emerging from the womb can be known. "Categories" refers to all the newly arising moments within a single retribution from after emergence from the womb down to old age and death, all of which are called birth.
