(30) The Buddha continued : “ O Ratnakuta, beings of all kinds are the Buddha-world of the Bodhisattvas. And why ? A Bodhisattva establishes his world according to the beings who are to be taught; he establishes his world according to the beings who are to be disciplined; he establishes his world according to whether or not beings are to enter into the wisdom of Buddha; he establishes his world according to whether or not beings through any world awaken the faculties of the Bodhisattva. And why ? That the Bodhisattva establishes these lands of purity is to benefit all beings. Just as a man can freely build a palace upon a vacant land as he wills, but not in the sky where such things are not possible; so the Bodhisattva wishes to establish his world in order to perfect all beings, for he cannot establish his Buddha-land in the emptiness of sky.
