8.601

七地以前決定性者，有受此性故，今此中說二乘無學、八地以去受變易生，決定故說；其前三果及七地前，不決定受變易生死，故不說之，此三種定故說之也。西方有解如前卷末已略解訖，以有菩薩初地即能伏諸煩惱故，初地得，如滅定說；或有乃至八地方得，謂有唯受分段非變易，謂諸凡夫，四果定性；或唯受變易非分段，謂二乘無學不定性者，八地以上菩薩或亦受分段，亦受變易，謂前三果不定性，七地已前此句由自在故，煩惱未盡故。若依煩惱障有漏業感生死名分段，即麁易知，若由無漏所知障助所感生死，即名變易，細難知故。故七地已前，代諸有情受三塗苦，乃是實身，易可知故；八地以去乃至化身，如佛救生化作身故，《大智度論》云：八地捨虫身者，捨分段也。

Those prior to the seventh stage who are of definitive lineage include those who undergo this nature; therefore, here it is said that the two vehicles' aśaikṣas and those from the eighth stage onward undergo transformation birth, stating this because it is definitive. The first three fruits and those prior to the eighth stage do not definitively undergo transformation saṃsāra, so they are not mentioned; these three kinds are stated because they are definitive. There is an explanation in the West, as already briefly explained at the end of the preceding fascicle, that because there are bodhisattvas who are already capable of subduing all afflictions in the first stage, they attain it in the first stage, as explained regarding the meditative attainment of cessation; or some only attain it up to the eighth stage. That is to say, some undergo only segmented limitation and not transformation, namely all ordinary beings and those of the four fruits of definitive lineage; some undergo only transformation and not segmented limitation, namely the two vehicles' aśaikṣas of indefinite lineage and bodhisattvas from the eighth stage onward; or some undergo both segmented limitation and transformation, namely the first three fruits of indefinite lineage and those prior to the eighth stage—this clause is because of their mastery, while their afflictions are not yet exhausted. If one relies on the saṃsāra brought about by the afflictive hindrances and contaminated karma, it is named segmented limitation, which is coarse and easy to know; if it is the saṃsāra brought about by the undefiled, aided by cognitive hindrances, it is named transformation, which is subtle and difficult to know. Therefore, prior to the eighth stage, undergoing the sufferings of the three evil destinies on behalf of sentient beings is a real body, which is easy to know; from the eighth stage onward, it extends even to transformation bodies, just as the Buddha creates transformation bodies to rescue living beings. The Da zhidu lun states: 'In the eighth stage, shedding the insect body' refers to shedding segmented limitation.
