俱但緣一事者，有漏、無漏二他心智俱緣一事，謂緣心時不緣心所，緣受等時不緣想等。論云：「諸他心智有決定相，謂唯能取欲、色界繫（簡無色界，不知上故）及非所繫（緣無漏故也）他相續中（緣他身也），現在（不緣過未）同類（法分他心智知法分心，類分他心智知類分心，有漏他心智知有漏心，無漏他心智知無漏心也）心、心所法（不緣色故）一實自相，為所緣境（唯緣一事，名為一也。不緣假法，名實也。不緣共相，名自相也），空、無相、不相應（三解脫分別也。謂緣道諦作四行相，與無願解脫門相應。不作空非我行，不與空解脫門相應。不作滅諦四行相，不與無相解脫門相應之也），盡、無生所不攝（他心智是見性故，彼不攝之），不在見道、無間道中（修他心智容預時修，見道速疾，非容預故，無間道中正斷惑故，亦非容預，故彼二位無他心智），餘所不遮，如應容有（餘修道位加行、解脫、勝進三道，此位不遮容有他心智也。已上論文也）。」

As for "both take only a single thing as object": both defiled and undefiled telepathic knowledges take only a single thing as their object, meaning that when taking mind as object it does not take mental factors, and when taking sensation and so forth as object it does not take ideation and so forth. The treatise says: "All telepathic knowledges have determinate characteristics: they only apprehend the real, individual characteristic of a single present mental factor or mind of the same category in the continuum of another person that is bound to the desire or form realms (excluding the formless realm, because one does not know what is higher) or unbound (because it takes the undefiled as its object), taking it as their cognitive object (because it takes only a single thing as object, it is called 'single'; because it does not take provisional entities as object, it is called 'real'; because it does not take common characteristics as object, it is called 'individual characteristic'); it does not correspond with emptiness or signlessness (distinguishing among the three gates of liberation: taking the truth of the path as object and forming four aspects, it corresponds with the wishless gate of liberation; not forming the aspects of emptiness and non-self, it does not correspond with the emptiness gate of liberation; not forming the four aspects of the truth of cessation, it does not correspond with the signless gate of liberation); it is not subsumed under [the knowledges of] destruction and non-arising (because telepathic knowledge is of the nature of seeing, they do not subsume it); it does not occur during the path of seeing or the uninterrupted path (cultivating telepathic knowledge is practiced in times of leisure; the path of seeing is swift, not leisurely, and during the uninterrupted path one is directly cutting off afflictions, so it is also not leisurely; hence telepathic knowledge is absent in these two stages); the rest are not excluded, and it may be present as appropriate (in the remaining three paths of the path of cultivation—preparatory, liberation, and excellence paths—it is not excluded and telepathic knowledge may be present; the above is the text of the treatise)."
