菩薩瓔珞本業經 1.51

1.51

「佛子！十、為自在轉大法輪故。所謂菩薩三寶：菩薩爾時於第一義中道，智為覺寶。一切法無生動與，則用為法寶。常行六道與六道眾生和合，故名僧寶。轉一切眾生，流入佛海故。

"Buddha-son! Tenth is to turn the great wheel of Dharma with sovereignty, that is to say, the bodhisattva's three jewels: at that time, within the Middle Way of ultimate truth, the bodhisattva's wisdom is the jewel of enlightenment; the unarisen movement and bestowal of all phenomena is utilized as the jewel of Dharma; and constantly traversing the six destinies in harmony with the sentient beings of the six destinies is called the jewel of the Saṅgha. This is because they turn all sentient beings so that they flow into the ocean of the Buddha.
