無量壽經優婆提舍願生偈註 2.108

2.108

八地已上菩薩常在三昧，以三昧力身不動本處，而能遍至十方供養諸佛教化眾生。無垢輪者，佛地功德也。佛地功德無習氣煩惱垢，佛為諸菩薩常轉此法輪，諸大菩薩亦能以此法輪開導一切無暫時休息，故言常轉。法身如日，而應化身光遍諸世界也。言日未足以明不動，復言如須彌住持也。淤泥華者，經言「高原陸地不生蓮華，卑濕淤泥乃生蓮華。」此喻凡夫在煩惱泥中，為菩薩開導，能生佛正覺華。諒夫紹隆三寶，常使不絕。

Bodhisattvas of the eighth stage and above are constantly in samādhi. Through the power of samādhi, while their bodies do not move from their original place, they can go everywhere across the ten directions to make offerings to the Buddhas and educate and transform sentient beings. 'The immaculate wheel' refers to the merits of the Buddha-stage. The merits of the Buddha-stage are free from the defilements of latent afflictions. The Buddha constantly turns this wheel of Dharma for all bodhisattvas, and the great bodhisattvas can also use this wheel of Dharma to guide all [sentient beings] without a moment's rest; hence it is said that it 'constantly turns.' The Dharma body is like the sun, and the light of its adaptive transformation body shines universally throughout all worlds. Saying 'the sun' is not yet sufficient to make clear that it does not move; therefore it is further said that it 'dwells and sustains like Mount Sumeru.' As for 'the lotus in the mire,' the sūtra states: 'Lotuses do not grow on high plateaus and dry land; it is in low, wet mire that lotuses grow.' This is an analogy for ordinary beings who, while within the mire of afflictions, are guided by the bodhisattva and can give birth to the flower of the Buddha's correct awakening. Truly, they carry on and exalt the Three Jewels, causing them never to end.
