三彌勒經疏 1.196

1.196

言來意有二：一為廣顯彌勒人間弘化故、二為化下下遲晚流令得度脫故。何以故？前略雖示慈氏如來下人教化，令上中人殖善本，而未廣辨慈氏威力，令最下根智祈聖心故。以此二義，《下生經》次說此經也。

Regarding the intention of its delivery, there are two: first, to broadly reveal Maitreya's propagation and transformation in the human realm; second, to transform the lowest of the low and the tardy stream [of beings] so that they obtain deliverance. Why is this? Although previously it was briefly shown that the Tathāgata Maitreya descends among humans to teach and transform, causing those of superior and middling faculties to plant good roots, it did not broadly explain Maitreya's majestic power to lead those of the lowest faculties and understanding to aspire to the holy mind. By virtue of these two points, this sūtra is spoken following the *Descent Sūtra*.
