Why we should daily hear a Srila Prabhupada lecture

God is known to be unconquerable, but one who submissively hears the words of a self-realized soul conquers the unconquerable. The conclusion is that if one is serious about liberation, he not only should execute the occupational duties of varṇāśrama-dharma but should also engage in bhakti-yoga by beginning hearing from a realized soul. This process will help the devotee conquer the unconquerable Supreme Personality of Godhead and become His associate after giving up the material body.

(SB 4.24.53p)

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.
