瑜伽論記 14.25

14.25

今解：前為加行道已成然未決定尚輕是故，以去重發心是中品則無間道，後若作此事已成上品別作發無表。

The current explanation: The prior state constitutes the path of preparation, which is accomplished but not yet determined and still light; thereafter, repeatedly generating the mind is of middling grade, which is the uninterrupted path; later, if one actually performs this task, it becomes superior grade, separately acting to initiate non-manifest [action].
