仁王般若經疏 2.26

2.26

白佛言：「云何菩薩本業清淨化眾生？」佛言：「從一地乃至後一地，自所行處及佛行處一切知見故。本業者，若菩薩住百佛國中，作閻浮四天王，修百法門，二諦平等心化一切眾生。若菩薩住千佛國中，作忉利天王，修千法門，十善道化一切眾生。若菩薩住十萬佛國中作炎天王，修十萬法門，四禪定化一切眾生。」

[King Prasenajit] said to the Buddha: "How does the purification of a bodhisattva's fundamental karma transform sentient beings?" The Buddha said: "Because from one ground up to the subsequent ground, one has complete knowledge and vision of the places traversed by oneself and the places traversed by the buddhas. As for the fundamental karma: if a bodhisattva abides in a hundred buddha-lands, they act as the four heavenly kings of Jambūdvīpa, cultivate a hundred dharma-gates, and transform all sentient beings with a mind of equality toward the two truths. If a bodhisattva abides in a thousand buddha-lands, they act as the king of Trāyastriṃśa Heaven, cultivate a thousand dharma-gates, and transform all sentient beings with the path of the ten virtuous actions. If a bodhisattva abides in a hundred thousand buddha-lands, they act as the king of Yāma Heaven, cultivate a hundred thousand dharma-gates, and transform all sentient beings with the four dhyāna concentrations."
