The Māyāvādī philosophers say, brahma satyaṁ jagan mithyā: Brahman, the living being, is factual, but his present bodily situation is false. According to the Vaiṣṇava philosophy, however, the present situation is not false but temporary. It is like a dream. A dream does not exist before one falls asleep, nor does it continue after one awakens. The period for dreaming exists only between these two, and therefore it is false in the sense that it is impermanent. Similarly, the entire material creation, including our own creation and those of others, is impermanent. We do not lament for the situation in a dream before the dream takes place or after it is over, and so during the dream, or during a dreamlike situation, one should not accept it as factual and lament about it. This is real knowledge.
