俱舍論疏 9.100

論「為得種種至此位名取」，此出第九取支體也。「周遍馳求」，此簡前也。「此位名取」，正出取體。准《婆沙》云「五支時心、心所法染污，餘是染不染者，故知起染時名為取支，餘位非也。愛亦如是，初能馳求資財及婬境，故名為取。」《婆沙》二十三引《施設論》云「云何名取？謂由三愛四方追求，雖涉多危嶮而不辭勞倦。然未為後有起善、惡業，是名取蘊位。」

The treatise says: "In order to obtain various... this state is named grasping (upādāna)." This presents the intrinsic nature of the ninth link, upādāna. "Running about in all directions to seek" excludes what precedes. "This state is named upādāna" directly presents the intrinsic nature of upādāna. According to the Vibhāṣā: "At the time of the five links, the mind and mental factors are defiled; the remainder are defiled and undefiled." Therefore we know that when defilement arises it is named the link of upādāna, whereas other states are not. Craving is also like this: because one is first able to run about seeking wealth and sexual objects, it is named upādāna. Fascicle 23 of the Vibhāṣā quotes the Prajñaptiśāstra: "What is named upādāna? It means running about in the four directions on account of the three cravings, shrinking neither from toil nor weariness though treading through many perils, yet not having aroused good or bad karma for subsequent existences; this is named the state of the upādāna skandhas."
