SB 1.7 - Hearing Bhāgavatam produces prema
Simply by giving aural reception to Śrīmad Bhāgavatam, the feeling for loving devotional service to Kṛṣṇa, the Supreme Person (kṛṣṇe parama-pūruṣe), sprouts up (utpadyate) to extinguish the fire of lamentation, illusion and fearfulness (śoka-moha-bhayāpahā). Simply by hearing Bhāgavatam, prema arises. What to speak then of the greater effect if one engages others in hearing it. And what greater effect speaking it must have! And what even greater effect will engaging others in speaking it produce!
There are various senses, of which the ear is the most effective, which works even when one is asleep. The importance of hearing is mentioned here in connection with attaining the highest perfection of life. Everyone is full of lamentation chasing after the mirage of illusory things and being always afraid of his supposed enemy. But by hearing Bhāgavatam, one gets attachment to Kṛṣṇa and develops pure love for Him. The living entities are prakṛti while the Lord is puruṣa, and thus love exists between them. Loving devotional service begins with hearing about the Lord.
The transcendental sound vibration is so powerful that it removes at once all material affections. Under illusion one accepts the material body as an actual fact. Even in the most developed stage of human life, the same illusion prevails in the form of many isms and divides the loving relation with the Lord and thereby divides the loving relation between man and man. By hearing the subject matter of Bhāgavatam the false complexity of materialism is removed. One can have direct connection with the Supreme Personality of Godhead Śrī Kṛṣṇa, and attain the highest perfection of life by transcending worldly miseries, illusion and fearfulness. Hearing Bhāgavatam captures the Lord in the heart, and the Lord is captured only by prema, which is the result of sādhana-bhakti. Thus hearing Bhāgavatam produces prema.
