成唯識論演祕 5.81

5.81

釋曰：經中雙明未至、根本，離生喜樂滋潤其身，是初門也，周遍等下是後門也，故知十一，喜是其一。《顯揚》、《對法》大同不錄。

Explanation: The sūtra explains both the unarrived and the fundamental: 'permeating his body with joy and pleasure born of seclusion' is the first passage; 'thoroughly permeating' and below is the later passage. Therefore we know that among the eleven, joy is one. The Prakaraṇāryavācā and the Abhidharmasamuccaya are largely identical and are not recorded here.
