瑜伽論記 14.16

14.16

Regarding "there are only spoken sounds, which are called vocal manifest action": this excludes the Sarvāstivāda position that sound itself is vocal action. Here it says there are only spoken sounds; initiated by volitional action, they are called vocal manifest action, whose substance is purely indeterminate, unlike the Hinayāna where the substance of the action extends to the three natures. Regarding "there is only initiating mind and formative volition, which are called mental manifest action": this states that volition is taken as mental action; mental action also initiates body and speech, taking volition as action; action is form but is nominally designated, not that there is a separate form called action, etc.
