釋禪波羅蜜次第法門 5.113

5.113

第一、釋名者，次初禪後，故說二禪。既離覺觀，於第二心得勝支功德，故名二禪，亦名無覺無觀三昧。所以者何？得中間禪，斷覺，二禪內淨發，故斷觀，亦名聖默然定。以覺觀語言滅故，故名默然。若得無漏正慧，入此定故，即名聖默然，《地持論》中說名「喜俱禪」。此定生時，與喜俱發故。

First, explaining the name: coming after the first dhyāna, it is called the second dhyāna. Having abandoned vitarka and vicāra, one attains the virtues of superior factors in the second mind, hence it is called the second dhyāna; it is also called the samādhi without vitarka and without vicāra. Why? Attaining the intermediate dhyāna, one severs vitarka; with the arising of inner purification in the second dhyāna, one severs vicāra; it is also called the absorption of noble silence. Because the speech of vitarka and vicāra is extinguished, it is called silence. Because one enters this absorption having attained undefiled correct wisdom, it is called noble silence; in the Bodhisattvabhūmi (Dichi lun), it is called the 'dhyāna accompanied by joy,' because when this absorption arises, it arises together with joy.
