瑜伽論記 10.14

10.14

言無滯智者，有兩釋。一云，即前二智作用揵利故名無滯智。一云，唯約後得智上作用揵利義說無滯，無有別體。

Regarding 'unobstructed wisdom', there are two explanations. One says: It is called unobstructed wisdom because the operation of the preceding two wisdoms is sharp and keen. Another says: Unobstructed is spoken solely with reference to the sharp and keen operation of subsequent wisdom; it has no separate essence.
