The potency of hearing Srimad Bhagvatam

By sufficient hearing of Śrīmad-Bhāgavatam, the polluted aim of life, namely lording it over matter, will subside…By the process of bhakti-yoga, directly accepted by sufficient hearing of the transcendental message of the Lord, the material contamination is directly eliminated… And by practicing bhakti-yoga, if the performer is not purified from the material contamination, he must be a pseudodevotee. For such an imposter there is no remedy for being freed from material entanglement.

(SB 2.2.37p)
