首楞嚴義疏注經 1.555

1.555

四禪、四空及滅受想，名為九定。通名次第者，若入禪時智慧深利，能從一禪入一禪，心心相續，更無異念可間雜故。然修此定，能成無漏；今言不得漏盡者，乃通指世間有漏心修欲界，未至及四禪四空定耳。凡夫修禪，多生味著，隨禪感果，不出三界，故非無漏。非別指於滅盡等九，亦可別斥前之九定。雖通無漏，俱是不了。

"The four dhyānas, the four formless attainments, and the cessation of feeling and perception are called the nine samādhis. They are collectively called 'successive' because when entering dhyāna, one's wisdom is deep and sharp, able to enter one dhyāna from another, thought continuing upon thought, without any divergent thoughts intermingling. Now, cultivating these samādhis can bring about the outflow-free state; that it now says they do not attain the exhaustion of outflows refers generally to the worldly cultivation of the desire realm, the unarrived [concentration], and the four dhyānas and four formless absorptions with an outflow-tainted mind. When ordinary beings cultivate dhyāna, they mostly generate taste and attachment, experiencing fruits in accord with dhyāna without transcending the three realms; hence they are not outflow-free. It does not specifically refer to the nine such as cessation; or alternatively, it may specifically rebuke the preceding nine samādhis: though they are accessible to the outflow-free, all are not ultimate."
