Śaṅkarācārya's commentary

Pleasant and unpleasant objects can cause pleasure and pain to them only who regard the body as the Self, not to him who sees the pure Self, since the latter never comes by pleasant and unpleasant objects. He is undoubtingly conscious that the Self is one, homogeneous, and spotless in all creatures. He is free from delusion. He rests in Brahman described above; that is, he does no action, he has renounced all action.
