瑜伽論記 3.146

3.146

The first four phrases describe the two modes of birth from the womb and from eggs; the next phrase describes the two modes of birth from moisture and apparition. This universally adduces a single body as the limb of birth. As for the sudden arising of bodily parts: the previous fascicle of this treatise and other sūtras and treatises all state that apparitional birth arises suddenly, while in the other three modes of birth the sense faculties appear gradually. Now, stating that birth from moisture also arises suddenly allows us to know that in birth from the womb and eggs the sense faculties arise gradually, in apparitional birth they arise suddenly, and birth from moisture encompasses both gradual and sudden. 'Sudden' refers to cases such as moisture-born worms arising from decaying moisture before alteration, whose faculties are fully equipped suddenly. The lower five phrases apply to all four modes of birth. 'Attainment of aggregates' refers to the arising of the aggregate's substance; 'attainment of realms' refers to the seeds of the aggregates, the nature of aggregate cause-conditions; attainment of aggregates is the maturation of manifest activity, attainment of realms is the maturation of seeds, and attainment of bases applies to both manifest activity and seeds, with the maturation of the remaining three conditions.
