宋高僧傳 13.39

13.39

梵語「禪那」，華言「念修」也。以其觸情念而無念，終日修而無修。又云「正定」也，「正受」也；正則廓然冥而定矣，正受簡邪思惟、增遍計故。所以「奢摩他」以寂靜故，「三摩提」以觀如幻故；若「禪那」者，俱離靜、幻故，始云：「菩薩不住此岸，不住彼岸，而度眾生令登彼岸」也。若然者，諸聖住處既如彼，諸聖度生復若何？

The Sanskrit word "dhyāna" is translated into Chinese as "contemplative cultivation." This is because one encounters feelings and thoughts yet is without thought, and cultivates all day yet is without cultivation. It is also called "correct concentration" (samādhi) and "correct reception" (samāpatti); "correct" means that one is vast, obscure, and concentrated, while "correct reception" excludes erroneous thinking and eliminates pervasive conceptualization. Therefore, śamatha is for tranquility, and samāpatti is for contemplating things as illusory; as for dhyāna, it is free from both tranquility and illusion, which is why it is said: "Bodhisattvas do not abide on this shore, nor on the other shore, yet cross sentient beings over to reach the other shore." If so, since the dwelling place of all the sages is like that, how do the sages cross sentient beings over?
