It is our duty to understand the Supreme Personality of Godhead, whose lotus feet are worshiped by all the Vedas. One who does not understand Him and is proud of a false understanding of the Vedānta is actually a fool. Mundane attempts at academic knowledge are simply another type of foolishness. As long as one cannot understand the cosmic manifestation as a representation of the three modes of material nature, he must be considered to be in the darkness of inebriety and caught in the duality of this material world. A person who is in perfect knowledge of the Vedānta becomes a servitor of the Supreme Lord, who is the maintainer and sustainer of the whole cosmic manifestation. As long as one is not transcendental to the service of the limited, he cannot have knowledge of the Vedānta.
As long as one is within the limited jurisdiction of fruitive activities or is involved in mental speculation, he may perhaps be eligible to study or teach theoretical knowledge of the Vedānta-sūtra, but he cannot understand the supreme, eternal, transcendental (completely liberated) vibration of Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. One who has achieved perfection in chanting this transcendental vibration does not have to separately learn the philosophy of the Vedānta-sūtra. According to the teachings of Caitanya Mahāprabhu, the bona fide spiritual master, those who do not understand that this transcendental vibration is nondifferent from the Supreme, yet who try to become Māyāvādī philosophers expert in the Vedānta-sūtra, are all fools. Studying the Vedānta-sūtra by one's own efforts (the ascending process of knowledge) is a sign of foolishness. On the other hand, he who has attained a taste for chanting this transcendental vibration has actually reached the conclusion of the Vedānta. In this connection, there are two verses in Śrīmad-Bhāgavatam which are very instructive.
