阿彌陀經疏 1.20

1.20

經者，梵言修多羅，義翻契經者，詮表義理契合人心，即契理契機也。經者，《佛地論》云：能貫能攝故名為經，以佛聖教，貫穿所應說義、攝持所化生故。釋名竟。

The word "sūtra" is sūtra in Sanskrit; its translation according to meaning as qìjīng (concordant scripture) means that it expresses the principle and accords with the human mind—that is, it accords with principle and accords with capacity. As for "sūtra", the Buddhabhūmi-śāstra states: "Because it can string together and hold together, it is called a sūtra; for the sacred teaching of the Buddha strings together the meanings that should be explained and holds together the beings that are to be transformed." The explanation of the title is concluded.
