1.35

三、寂用無礙者，雖現如是無邊自在，然不作意、不起念慮，常在三昧，不礙起用。〈不思議品〉云「於一念中悉能示現一切三世佛，教化一切眾生，而不捨離諸佛寂滅無二三昧，是為諸佛不可譬喻、不可思議境界。如末尼雨寶、天鼓出聲，皆無功用，任運成就。」

Third, the unobstructed unity of quiescence and function: although manifesting such boundless sovereignty, [the Tathāgata] makes no mental effort and generates no deliberate thoughts, always abiding in samādhi without obstructing the arising of function. The 'Inconceivable Chapter' says: 'In a single thought-moment, he is able to manifest all the Buddhas of the three periods of time and transform all sentient beings, yet without abandoning the non-dual samādhi of quiescence of all Buddhas. This is the incomparable, inconceivable realm of all Buddhas. Just as a maṇi-jewel rains down treasures and a celestial drum emits sounds, all are without purposive exertion, being accomplished effortlessly.'
