8.476

四者、受斷樂，即以想受滅定為樂體，即是厭心種上立滅定，滅定位中。所有厭心種子皆此樂體。論云：以定為樂體故。

The fourth is the bliss of the cessation of feeling. That is, it takes the concentration of cessation of ideation and feeling as the entity of bliss; namely, the concentration of cessation is established upon the seeds of the mind of revulsion. In the state of cessation, all seeds of the mind of revulsion are the entity of this bliss. The treatise says this because it takes concentration as the entity of bliss.
