俱舍論疏 28.107

28.107

論「由初二樂輕安攝故」，有部答也。《唯識論》初、二喜、樂是一受，所悅身、心異，立兩名也。

On the treatise passage: "Because the pleasure in the first two is subsumed under pliancy": this is the Sarvāstivādin's answer. In the Vijñaptimātratāsiddhi, joy and pleasure in the first and second [dhyānas] are a single feeling; because the bodily and mental gladdening differ, two names are established.
