第二復次，云思惟所緣者，觀所治障而生厭離，是對治支。受用所緣者，喜樂對緣而有受用，是利益支，於緣不散，是心一支。

In the second explanation, 'reflecting on the intentional object' means observing the hindrances to be counteracted and generating revulsion; this is the counteractive factor. 'Enjoying the intentional object' means that joy and bliss experience enjoyment in relation to the object; this is the beneficial factor. Being undistracted regarding the object is the factor of one-pointedness of mind.
