CC Adi-lila

Those who are addicted to fruitive activities and speculative knowledge cannot understand the value of the holy name of Lord Kṛṣṇa, which is always completely pure, eternally liberated and full of spiritual bliss. One who has taken shelter of the holy name of the Lord, which is identical with the Lord, does not have to study Vedānta philosophy, for he has already completed all such study.

CC Adi 7.72, Purport:

Only fools give up the service of the spiritual master and think themselves advanced in spiritual knowledge. In order to check such fools, Caitanya Mahāprabhu Himself presented the perfect example of how to be a disciple. A spiritual master knows very well how to engage each disciple in a particular duty, but if a disciple, thinking himself more advanced than his spiritual master, gives up his orders and acts independently, he checks his own spiritual progress. Every disciple must consider himself completely unaware of the science of Kṛṣṇa and must always be ready to carry out the orders of the spiritual master to become competent in Kṛṣṇa consciousness. A disciple should always remain a fool before his spiritual master. Therefore sometimes pseudo spiritualists accept a spiritual master who is not even fit to become a disciple because they want to keep him under their control. This is useless for spiritual realization.

One who imperfectly knows Kṛṣṇa consciousness cannot know Vedānta philosophy. A showy display of Vedānta study without Kṛṣṇa consciousness is a feature of the external energy, māyā, and as long as one is attracted by the inebrieties of this ever-changing material energy, he deviates from devotion to the Supreme Personality of Godhead. An actual follower of Vedānta philosophy is a devotee of Lord Viṣṇu, who is the greatest of the great and the maintainer of the entire universe. Unless one surpasses the field of activities in service to the limited, one cannot reach the unlimited. Knowledge of the unlimited is actual brahma-jñāna, or knowledge of the Supreme. Those who are addicted to fruitive activities and speculative knowledge cannot understand the value of the holy name of Lord Kṛṣṇa, which is always completely pure, eternally liberated and full of spiritual bliss. One who has taken shelter of the holy name of the Lord, which is identical with the Lord, does not have to study Vedānta philosophy, for he has already completed all such study.

One who is unfit to chant the holy name of Kṛṣṇa but thinks that the holy name is different from Kṛṣṇa and thus takes shelter of Vedānta study in order to understand Him must be considered a number one fool, as confirmed by Caitanya Mahāprabhu by His personal behavior, and philosophical speculators who want to make Vedānta philosophy an academic career are also considered to be within the material energy. A person who always chants the holy name of the Lord, however, is already beyond the ocean of nescience, and thus even a person born in a low family who engages in chanting the holy name of the Lord is considered to be beyond the study of Vedānta philosophy.
