若在定地乃至是名為伺者，景云：此尋伺行既有麁細不得俱生，八正道中正思惟是尋，尋以思及慧為性，正見亦是慧，一念中無二慧並，俱可義說為二，亦可正思惟以思為性，正見以慧為性，別體並生。

Regarding "If in the stage of concentration... up to... this is called reflection," Jing says: Since the operations of this investigation and reflection have coarseness and subtlety, they cannot arise simultaneously. In the eightfold noble path, right thought is investigation; investigation has thinking (cetanā) and wisdom (prajñā) as its nature; right view is also wisdom. In a single thought-moment two wisdoms cannot be concurrent; both may theoretically be explained as two. Alternatively, right thought has thinking as its nature, and right view has wisdom as its nature; distinct entities arise concurrently.
