2.423

"Purifying the path of the ten wholesome deeds, they receive the blessings of gods and humans; cultivating the four immeasurables, they open the path to the Brahmā heavens." The ten wholesome deeds are the causes for the desire heavens, and the immeasurables are the causes for the Brahmā heavens; sentient beings lack roots for world-transcendence, so [bodhisattvas] receive them with the wholesome deeds of humans and gods to keep them from the three evil paths. This is the upāya of the mahāsattva.
