俱舍論疏 28.30

28.30

論「具伺喜樂至而不與尋俱」，明初定具尋、伺、喜、樂也。頌但言「伺」，以表尋俱，以伺有喜、樂，定有尋故。以中間靜慮無喜、樂故。自餘有伺，示有於尋。

The Śāstra says: "Possessing investigation, joy, and pleasure [...] but is not accompanied by vitarka." This clarifies that the first dhyāna possesses vitarka, vicāra, prīti, and sukha. The verse only states "vicāra" in order to indicate that it is accompanied by vitarka, because where vicāra has joy and pleasure, it must have vitarka, and because the intermediate dhyāna lacks joy and pleasure. In all other cases where there is vicāra, it indicates the presence of vitarka.
