釋禪波羅蜜次第法門 5.16

5.16

復次，言初禪者，亦名有覺有觀三昧，為有人疑言覺觀心中無定，是故佛說覺觀三昧。《地持論》說：「名覺觀俱禪。」此禪發時，必與覺觀俱發，亦名聖說法定。此定內有覺觀語言道未斷故，與說法之名，如是等種種名字不同。

Furthermore, regarding the first dhyāna, it is also called the samādhi with vitarka and vicāra. Because some people doubted whether there could be absorption in a mind with vitarka and vicāra, the Buddha therefore spoke of the samādhi with vitarka and vicāra. The Bodhisattvabhūmi states: "It is named the dhyāna associated with vitarka and vicāra." When this dhyāna arises, it must arise together with vitarka and vicāra; it is also called the absorption of noble Dharma-teaching. Because the path of speech consisting of vitarka and vicāra has not yet been severed within this absorption, it is given the name "teaching the Dharma." Such are the various different names.
