大方廣圓覺修多羅了義經 1.111

1.111

「若經夏首，三月安居，當為清淨菩薩止住，心離聲聞不假徒眾。至安居日即於佛前作如是言：『我比丘、比丘尼、優婆塞、優婆夷某甲，踞菩薩乘修寂滅行，同入清淨實相住持，以大圓覺為我伽藍，身心安居，平等性智，涅槃自性，無繫屬故。今我敬請不依聲聞，當與十方如來及大菩薩三月安居，為修菩薩無上妙覺大因緣故不繫徒眾。』善男子！此名菩薩示現安居，過三期日隨往無礙。善男子！若彼末世修行眾生求菩薩道入三期者，非彼所聞一切境界終不可取。

"If it coincides with the beginning of summer, the three months of the retreat should be observed as the dwelling of pure bodhisattvas, their minds detached from the śrāvakas, not relying on a community. When the day of the retreat arrives, one should state before the Buddha: 'I, the bhikṣu, bhikṣuṇī, upāsaka, or upāsikā named so-and-so, mounting the Bodhisattva Vehicle, practice the cultivation of quiescence and enter together into the preservation of pure true reality. Taking great perfect enlightenment as my saṅghārāma, my body and mind dwell peacefully within the wisdom of equality; for the self-nature of nirvāṇa has no attachment or bondage. Now I respectfully request not to depend on the śrāvakas, and wish to dwell in retreat for three months with the Tathāgatas and great bodhisattvas of the ten directions. For the sake of cultivating the great cause and condition of the unsurpassed, wondrous enlightenment of the bodhisattvas, I am not bound to a community.' Kulaputra, this is called the bodhisattva's manifestation of the retreat. When the days of the three periods have passed, one may go wherever one wishes without hindrance. Kulaputra, if those practicing sentient beings in the latter age who seek the bodhisattva path enter the three periods, any realm that they have not heard of must ultimately not be accepted.
