說無垢稱經疏 4.474

4.474

贊曰：下釋近久滅位。有三：初法說、次喻說、後合說。此法說也。菩薩生死為度有情，名依有情流轉生死。由依生死有情病故，菩薩亦病。若諸有情得離生死，菩薩乃差。

Commentary: Below explains the duration and the stage of eradication. There are three: first, an exposition in terms of Dharma; next, an exposition by analogy; finally, a concluding synthesis. This is the exposition in terms of Dharma. A bodhisattva enters saṃsāra to deliver sentient beings, which is called transmigrating in saṃsāra based on sentient beings. Because sentient beings are ill on the basis of saṃsāra, the bodhisattva is also ill. If sentient beings can be freed from saṃsāra, only then will the bodhisattva recover.
