法苑珠林 30.25

30.25

Also, the Mahāsaṃnipāta Sūtra says: At that time the youth Jayamati said to the Buddha, "World-Honoured One, the people of Buddha lands in other directions always say: 'The Sahā world is impure and defiled.' Yet I now always see it as pure." The Buddha said, "So it is, so it is. It is just as you have said. Furthermore, the bodhisattvas of this world may take on various forms of devas, humans, or animals to travel through Jambudvīpa, teaching and transforming sentient beings of such categories. To tame sentient beings as a human or deva is not difficult; but to tame sentient beings as an animal—that is truly difficult."
