Such knowledge in Krsna consciousness can be achieved by a faithful person who believes firmly in Krsna. One is called a faithful man who thinks that, simply by acting in Krsna consciousness, he can attain the highest perfection. This faith is attained by the discharge of devotional service, and by chanting  "Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare,"  which cleanses one's heart of all material dirt. Over and above this, one should control the senses. A person who is faithful to Krsna and who controls the senses can easily attain perfection in the knowledge of Krsna consciousness without delay.

Out of many standard and authoritative revealed scriptures, the  Bhagavad-gita  is the best. Persons who are almost like animals have no faith in, or knowledge of, the standard revealed scriptures; and some, even though they have knowledge of, or can cite passages from, the revealed scriptures, have actually no faith in these words. And even though others may have faith in scriptures like  Bhagavad-gita,  they do not believe in or worship the Personality of Godhead, Sri Krsna. Such persons cannot have any standing in Krsna consciousness. They fall down. Out of all the abovementioned persons, those who have no faith and are always doubtful make no progress at all. Men without faith in God and His revealed word find no good in this world, nor in the next. For them there is no happiness whatsoever. One should therefore follow the principles of revealed scriptures with faith and thereby be raised to the platform of knowledge. Only this knowledge will help one become promoted to the transcendental platform of spiritual understanding. In other words, doubtful persons have no status whatsoever in spiritual emancipation. One should therefore follow in the footsteps of great  acaryas  who are in the disciplic succession and thereby attain success.

One who follows the instruction of the  Gita , as it is imparted by the Lord, the Personality of Godhead Himself, becomes free from all doubts by the grace of transcendental knowledge. He, as a part and parcel of the Lord, in full Krsna consciousness, is already established in self-knowledge. As such, he is undoubtedly above bondage to action.
