成唯識論演祕 6.112

6.112

問：隨上八生，即顯不定得第四定，與《對法》論豈不相違？彼論第九作四句云：若已離色界欲者，一切皆能入無色界寂靜解脫定耶？設能入無色界寂靜解脫定者，一切已離色界欲耶！

Question: Being born in the upper eight [stages] as appropriate shows that it is not determined that they attain the fourth dhyāna; does this not contradict the Abhidharmasamuccaya-bhāṣya? The ninth fascicle of that treatise presents a fourfold proposition, saying: If one has already separated from desire of the form realm, can all enter the tranquil liberation-absorption of the formless realm? If one is able to enter the tranquil liberation-absorption of the formless realm, has everyone already separated from desire of the form realm?
