釋禪波羅蜜次第法門 5.7

5.7

今論色界根本正定，但說有四。若通方便中間，是則不定。若薩婆多人，說有未到地及中間禪，足四禪為六地定。若曇無德人，例不說有未來禪，而說有欲界定、中間禪，以為六地定。若《摩訶衍》及瞿沙所明，則具有欲界、未到地、中間禪，足四禪為七地定。此中融會，以義推之。

Now, discussing the fundamental, correct absorptions of the form realm, they are said to be only four. If one includes the expedient means and the intermediate [dhyānas], then it is variable. Followers of the Sarvāstivāda say that there are the anāgamya and intermediate dhyānas, adding them to the four dhyānas to make six stages of absorption. Followers of the Dharmaguptaka generally do not speak of the future [anāgamya] dhyāna, but speak of desire-realm absorption and intermediate dhyāna, taking them to be six stages of absorption. What the Mahāyāna [Treatise] and Ghoṣaka explain fully includes the desire-realm [concentration], anāgamya, and intermediate dhyāna, adding them to the four dhyānas to make seven stages of absorption. These should be harmonized and understood through reason.
