觀彌勒上生兜率天經贊 1.18

1.18

Question: The retributive fruit of the ten kings should be to become the lord of the fourth dhyāna; why then does one bound to one last birth reside in Tuṣita? In which heaven does a bodhisattva of the fifth ground definitely abide? Answer: If one determines the fruit based on the cause, he should be the lord of the fourth dhyāna; but to accord with going down below to carry out transformation, he renounces it to reside in Tuṣita. For the fifth ground determining its fruit, the position resides in the heaven of Tuṣita; in cultivating practices, one does not definitely abide in a single place, so why must he reside in Tuṣita? That [the bodhisattva] bound to one last birth dwells here while [the bodhisattva of] the fifth ground roams in transformation is also not contradictory. It is merely said that a bodhisattva is entitled to receive the ten positions, not that all bodhisattvas are definitively bound to receive them, since they renounce positions to cultivate practices in accordance with benefiting sentient beings.
