俱舍論疏 21.157

21.157

論「雖諸越界位至未立遍知」，釋疑難也。若雙因滅時必離俱繫，用無別故唯立四緣。越界之時必雙因離，如何雙因離外別立越界？答云：雖越界時必俱繫因，離色無色界、離下三地惑時，雖滅雙因而未越界，由此別立越界緣。非如離雙因必定俱繫離，若是俱繫離必定離雙因。

The Śāstra says: "Although at all stages of transcending the realm, down to: parijñā is not yet established." This resolves a doubt and objection. If extinguishing both causes necessarily implies release from conjoined bondage, and because of no difference in function only four conditions are established, then when transcending the realm both causes are necessarily released; why then is transcending the realm separately established outside the release of both causes? The answer says: although when transcending the realm both causes are necessarily bound together and released, when releasing the form and formless realms and releasing the afflictions of the lower three stages, both causes are extinguished yet the realm is not transcended; on account of this, the condition of transcending the realm is separately established. It is not like the release of both causes necessarily implying release from conjoined bondage, and if there is release from conjoined bondage it necessarily implies the release of both causes.
