Śrī Krsna, the Personality of Godhead, who is the Paramātmā [Supersoul] in everyone's heart and the benefactor of the truthful devotee, cleanses desire for material enjoyment from the heart of the devotee who has developed the urge to hear His messages, which are in themselves virtuous when properly heard and chanted.
"The Lord is so kind to us that He can be present before us personally in the form of transcendental sound, but unfortunately we have no taste for hearing and glorifying the Lord's name and activities. We have already discussed developing a taste for hearing and chanting the holy sound. It is done through the medium of service to the pure devotee of the Lord.
...The Lord is reciprocally respondent to His devotees. When He sees that a devotee is completely sincere in getting admittance to the transcendental service of the Lord and has thus become eager to hear about Him, the Lord acts from within the devotee in such a way that the devotee may easily go back to Him. The Lord is more anxious to take us back into His kingdom than we can desire. Most of us do not desire at all to go back to Godhead. Only a very few men want to go back to Godhead. But anyone who desires to go back to Godhead, Śrī Krsna helps in all respects."
Śrīmad Bhāgavatam 1.2.18
By regular attendance in classes on the Bhāgavatam and by rendering of service to the pure devotee, all that is troublesome to the heart is almost completely destroyed, and loving service unto the Personality of Godhead, who is praised with transcendental songs, is established as an irrevocable fact.
"Here is the remedy for eliminating all inauspicious things within the heart which are considered to be obstacles in the path of self-realization. The remedy is the association of the Bhāgavatas.
There are two types of Bhāgavatas, namely the book Bhāgavata and the devotee Bhāgavata. Both the Bhāgavatas are competent remedies, and both of them or either of them can be good enough to eliminate the obstacles.
...A devotee Bhāgavata is as good as the book Bhāgavata because the devotee Bhāgavata leads his life in terms of the book Bhāgavata and the book Bhāgavata is full of information about the Personality of Godhead and His pure devotees, who are also Bhāgavatas. Bhāgavata book and person are identical.
The devotee Bhāgavata is a direct representative of Bhagavān, the Personality of Godhead. So by pleasing the devotee Bhāgavata one can receive the benefit of the book Bhāgavata.
Human reason fails to understand how by serving the devotee Bhāgavata or the book Bhāgavata one gets gradual promotion on the path of devotion."
Śrīmad Bhāgavatam 1.2.20
Thus established in the mode of unalloyed goodness, the man whose mind has been enlivened by contact with devotional service to the Lord gains positive scientific knowledge of the Personality of Godhead in the stage of liberation from all material association.
"...A pure Vaisnava is a liberated soul and is transcendental even to the position of a brāhmana. In the material stage even a brāhmaṇa is also a conditioned soul because although in the brahminical stage the conception of Brahman or transcendence is realized, scientific knowledge of the Supreme Lord is lacking. One has to surpass the brahminical stage and reach the vasudeva stage to understand the Personality of Godhead Krsna.
The science of the Personality of Godhead is the subject matter for study by the postgraduate students in the spiritual line."
