仁王經疏 2.109

2.109

Question: Why does this text only speak of the ten bhūmis? Answer: The three stages of worthies prior to the bhūmis are worthy but not noble; the single stage of wondrous enlightenment has already surpassed bodhisattvas; therefore, among the causal stages, the answer is given according to what is superior. Next, distinguishing the two practices: first, their own range of practice, meaning the realm practiced by the ten bhūmis themselves; second, the range of practice of the Buddha, meaning the realm of practice of the stage of wondrous enlightenment. The preceding ten bhūmis only understand the range of practice of their own practice, while subsequently a single thought of vajra passes through both domains. Thus the lower sūtra says: "Attaining the samādhi of the exhaustion of principle, identical with the range of the Buddha's practice, like the realm of the Buddha," and so on extensively. Also, as the Yingluo jing says: "Buddha-son! The bodhisattva at that time abides in the gate of great tranquility [...] up to transcending the understanding of the ten bhūmis, sitting together with the Buddha." It is fully as stated there. Finally, saying "because of all knowledge and vision" explains the fulfillment of purity: that the practices of the ten bhūmis are pure in their original karma is entirely because they are generated by the power of knowledge and vision. Another says: from the first stage up to the subsequent buddha stage; the rest is as explained before.
