Śrī Bhaktisiddhānta Sarasvatī Gosvāmī Mahārāja comments in this connection, “One can become perfectly successful in the mission of his life if he acts exactly according to the words he hears from the mouth of his spiritual master.” This acceptance of the words of the spiritual master is called  śrauta-vākya , which indicates that the disciple must carry out the spiritual master’s instructions without deviation. Śrīla Viśvanātha Cakravartī Ţhākura remarks in this connection that a disciple must accept the words of his spiritual master as his life and soul. Śrī Caitanya Mahāprabhu here confirms this by saying that since His spiritual master ordered Him only to chant the holy name of Kṛṣṇa, He always chanted the Hare Kṛṣṇa  mahā-mantra  according to this direction ( ‘kṛṣṇa-mantra’ japa sadā—ei mantra-sāra ).
Kṛṣṇa is the origin of everything. Therefore when a person is fully Kṛṣṇa conscious it is to be understood that his relationship with Kṛṣṇa has been fully confirmed. Lacking Kṛṣṇa consciousness, one is only partially related with Kṛṣṇa and is therefore not in his constitutional position. Although Śrī Caitanya Mahāprabhu is the Supreme Personality of Godhead Kṛṣṇa, the spiritual master of the entire universe, He nevertheless took the position of a disciple in order to teach by example how a devotee should strictly follow the orders of a spiritual master in executing the duty of always chanting the Hare Kṛṣṇa  mahā-mantra . One who is very much attracted to the study of Vedānta philosophy must take lessons from Śrī Caitanya Mahāprabhu. In this age, no one is actually competent to study Vedānta, and therefore it is better that one chant the holy name of the Lord, which is the essence of all Vedic knowledge, as Kṛṣṇa Himself confirms in  Bhagavad-gītā :
vedaiś ca sarvair aham eva vedyo vedānta-kṛd veda-vid eva cāham
“By all the  Vedas  am I to be known; indeed I am the compiler of Vedānta, and I am the knower of the  Vedas .” (Bg. 15.15)
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
