定難文云：問：是誰難邪？答：三摩地相等者，謂是定所緣及因緣相兩家之難，定所變青等為境相還生於定。因緣相者，如後卷說，謂定資糧。十一難者，景云：經雖具明然此論中唯有其八，謂此中最初乃至亦復如是一難，從由不善守根門等故至釋鷃者為第二，彼唯思求至旋轉卒起為第三，彼於行時至與定為難為第四，或因定起慢是第五，或多言論是第六，或久尋思是第七，或因定生光明等相便捨內修諦現外色此第八難。

The text on the difficulties of concentration states: "Question: Difficulties to what are these? Answer: To the marks of samādhi, and so forth": this means they are difficulties to both the cognitive object of concentration and the marks of its causes and conditions. Blue and so forth transformed by concentration, as the marks of the objective sphere, in turn generate concentration. As for the marks of causes and conditions, as the later fascicle says, they refer to the requisites of concentration. Regarding the eleven difficulties, Jing says: Although the sūtra fully clarifies them, this treatise contains only eight: namely, here from the very beginning up to 'and likewise' is one difficulty; from 'due to not properly guarding the sense doors and so forth' to 'the quail' is the second; 'merely reflecting and seeking' up to 'abruptly arising while revolving' is the third; 'when one is walking' up to 'posing a difficulty to concentration' is the fourth; or arising conceit based on concentration is the fifth; or engaging in much talk is the sixth; or prolonged investigation is the seventh; or, because marks such as light arise based on concentration, immediately abandoning inner cultivation and directly manifesting outer forms is this eighth difficulty.
