仁王護國般若經疏 2.13

2.13

"All were arhats" is the third, clarifying their rank. If [we speak of] the Buddha in the Tripiṭaka [teaching], he is an arhat. Therefore the Abhiniṣkramaṇa-sūtra says: "At that time there were six arhats in the world"—five being the five individuals such as Ājñāta-Kauṇḍinya, and the one being precisely the Buddha. If in the shared teaching the three vehicles together practice the ten grounds, a bodhisattva of the seventh ground is precisely an arhat. If in the distinctive teaching, a bodhisattva of the ten dedications completely severs the afflictions of the three realms, being equal to an arhat. If in the perfect teaching, a bodhisattva of the ten faiths completely severs the afflictions of the three realms, also being equal to an arhat. Now, that "all were arhats" refers precisely to the bodhisattvas of the shared teaching. The Pañcaviṃśati says: "The wisdom or severance of an arhat is the bodhisattva's patience of the unarising dharmas." The Mahāsaṃnipāta also says: "A bodhisattva of great Dharma is called an arhat."
