23.269

又此諸行以於諸趣種種自體生起差別不成實故下，釋假我無常所以，如是由心如理作意，聞、解了故，聞慧也；等了故，思慧也；修諦了故，修慧也。即是聞慧歡喜，思慧等喜，修慧遍喜。

From "Furthermore, because these formations, in their various arisings of individual bodies within the diverse destinies, are unestablished in reality" downward, it explains the reason why the provisional self is impermanent. Due to thus attending properly with the mind, because of hearing and understanding, there is wisdom arisen from hearing; because of equal understanding, there is wisdom arisen from reflection; because of cultivating and understanding truth, there is wisdom arisen from cultivation. That is: joy through wisdom arisen from hearing, equal joy through wisdom arisen from reflection, and pervasive joy through wisdom arisen from cultivation.
