In plain words
Happiness and sorrow cannot be intrinsic properties of the Self, because the Self is changeless. Why then could they not belong to something other than the Self — or to the mind, since there is no relevant difference?
Close to the Sanskrit
Happiness and others are not properties of the Self, because of the changelessness of the Self; why [are they not] from another, or equally from the mind due to lack of distinction?
