The speculative argument of philosophers — “This world is real,” “No, it is not real” — is based upon incomplete knowledge of the Supreme Soul and is simply aimed at understanding material dualities. Although such argument is useless, persons who have turned their attention away from Me, their own true Self, are unable to give it up.
