There are some points in Sri Aurobindo's teaching which do not accord with the highest teachings of philosophy. Three of these are: his rejection of idealism in the Berkeleian sense, his advocacy of the Incarnation doctrine, and his acceptance of the possibility of mystical union with God. On the first point, it is impossible to escape from the truth that mind is the only reality we have ever known or can ever know, and therefore there is no place for matter in the scheme of things. In the second case, how can the infinite mind become confined in the finite flesh of no matter how divine an incarnation? In the third case, God as the Ultimate Reality is incomprehensible, intangible, absolute, and unthinkable. No human capacity, regardless of its power of stretching out, can so transcend its finite limitations as to achieve direct union with it. What the mystic does achieve, however, is union with his own individual divine soul--which is quite another matter. Still, Aurobindo is the most outstanding of recent Indian yogis.
