坐禪三昧經 2.18

2.18

世尊弟子習學五法門志求涅槃，有二種人：或好定多，以快樂故。或好智多，畏苦患故。定多者，先學禪法，後學涅槃。智多者，直趣涅槃。直趣涅槃者，未斷煩惱亦未得禪，專心不散直求涅槃，越愛等諸煩惱，是名涅槃。

Among the disciples of the Bhagavat who train in and practice the five Dharma gates with the resolve of seeking nirvāṇa, there are two kinds of people: some are inclined toward more samādhi because of its bliss; some are inclined toward more wisdom because they dread suffering and distress. Those with more samādhi first learn the methods of dhyāna and later learn nirvāṇa. Those with more wisdom proceed directly to nirvāṇa. As for those who proceed directly to nirvāṇa: having not yet severed the kleśas and having not yet attained dhyāna, they concentrate their minds without distraction and directly seek nirvāṇa, transcending craving and all other kleśas; this is called nirvāṇa.
