俱舍論疏 17.88

17.88

論「無惡意樂故至隨其所應」，無身業三，如文可解。「身心軟故，及無用故，隨其所應」者，《正理論》云「無誑心故，無虛誑語，或無用也。常和穆故，無離間語。言清美故，無麁惡語。北俱盧洲有三例：一意三業道唯成就不現行；二雜穢語通成就、現行；三身三業道、語三業道不成就亦不現行。」

In the passage of the śāstra from "Because there is no unwholesome intention" up to "as appropriate", the absence of the three physical karmas can be understood from the text. Regarding "because body and mind are soft, and because of lack of utility, as appropriate", the Nyāyānusāra says: "Because they have no deceptive mind, there is no false speech, or it is due to lack of utility. Because they are always harmonious, there is no divisive speech. Because their words are pure and pleasant, there is no harsh speech. Uttarakuru has three cases: first, the three mental courses of action are only possessed and not currently active; second, frivolous talk extends to both possession and current activity; third, the three physical courses of action and three vocal courses of action are neither possessed nor currently active."
