Generally Māyāvādī philosophers are perplexed before a learned Vaiṣṇava because the Māyāvādīs cannot explain the cause of bondage of the living entities. They simply say, "It is due to ignorance," but they cannot explain how the living entities can be covered by ignorance if they are supreme. The actual reason is that the living entities, although qualitatively one with the Supreme, are infinitesimal, not infinite. Had they been infinite, there would have been no possibility of their being covered by ignorance. Because the living entity is infinitesimal, he can be covered by an inferior energy. The foolishness and ignorance of the Māyāvādīs are revealed when they try to explain how the infinite can be covered by ignorance. It is offensive to attempt to qualify the infinite by arguing that He is subject to the spell of ignorance.
Although Śaṅkara attempted to cover the Supreme Lord by his Māyāvāda philosophy, he was simply following the order of the Supreme Lord. It should be understood that his teachings were a timely necessity but not a permanent fact. In the Vedānta-sūtra the distinction between the energy and the energetic is accepted from the very beginning. The second aphorism of the Vedānta-sūtra—janmādy asya yataḥ—-clearly states that the Supreme Absolute Truth is the source of all emanations. Thus the emanations are the energy of the Supreme, whereas the Supreme Himself is the energetic. Śaṅkara has falsely argued that if the transformation of energy is accepted, the Supreme Absolute Truth cannot remain immutable. But this is not true. Despite the fact that unlimited energy is always being generated, the Supreme Absolute Truth remains always the same. He is not affected by the emanation of unlimited energies. Śaṅkarācārya has therefore incorrectly established his theory of illusion.
Rāmānujācārya has discussed this point very nicely: "One may argue, "Since there was only one Absolute Truth before the creation of this material world, how is it possible that the living entities emanated from Him? If He were alone, how could He have produced or generated the infinitesimal living entities?" In answer to this question, the Vedas state that everything is generated from the Absolute Truth, everything is maintained by the Absolute Truth, and, after annihilation, everything enters into the Absolute Truth. This statement from the Upaniṣads makes it clear that when the living entities are liberated they enter into the supreme existence without changing their original constitutional position."
We must always remember that the Supreme Lord has His creative function and that the infinitesimal living entities have their creative functions also. It is not that their creative function is lost when they are liberated and enter into the Supreme after the dissolution of the material body. On the contrary, the creative function of the living entity is properly manifested in the liberated state. If the living entity's activities are manifest even when he is materially conditioned, then how is it possible for his activities to stop when he attains liberation? The living entity's entering the state of liberation may be compared to a bird entering a tree, or an animal entering the forest, or a plane entering the sky. In no case are activities stopped.
When explaining the second aphorism of the Vedānta-sūtra, Śaṅkara has most unceremoniously tried to explain that Brahman, or the Supreme Absolute Truth, is impersonal. He has also cunningly tried to switch the doctrine of by-products into the doctrine of change. For the Supreme Absolute Truth, there is no change. It is simply that a by-product results from His inconceivable powers of action. In other words, a relative truth—a by-product—is produced out of the Supreme Truth. For example, when a chair is produced out of crude wood, it is said that a by-product is produced. The Supreme Absolute Truth, Brahman, is immutable, and when we find a by-product—the living entity or this cosmic manifestation—it is a transformation of the Supreme's energies, or a by-product of the Supreme. It is like milk being transformed into yogurt. In this way, if we study the living entities in the cosmic manifestation, it will appear that they are not different from the original Absolute Truth, but from the Vedic literature we understand that the Absolute Truth has varieties of energy and that the living entities and the cosmic manifestation are but a demonstration of His energies. The energies are not separate from the energetic; therefore the living entity and cosmic manifestation are inseparable truths, part of the Absolute Truth. Such a conclusion regarding the Absolute Truth and the relative truth should be acceptable to any sane man.
