When I first began reading this verse from the Srimad Bhagavatam this morning, I thought it was just about hearing, but as I read and re read the purport, it was also about love.
“Simply by giving aural reception to this Vedic literature, the feeling for loving devotional service to Lord Kṛṣṇa, the Supreme Personality of Godhead, sprouts up at once to extinguish the fire of lamentation, illusion and fearfulness.” (Srimad Bhagavatam 1.7.7.)
There are various senses, of which the ear is the most effective. This sense works even when a man is deep asleep. One can protect himself from the hands of an enemy while awake, but while asleep one is protected by the ear only. The importance of hearing is mentioned here in connection with attaining the highest perfection of life, namely, getting free from three material pangs…
…And it is definitely suggested herein that simply by hearing the message of Śrīmad-Bhāgavatam one gets attachment for the Supreme Personality of Godhead Śrī Kṛṣṇa, and as soon as this is effected the symptoms of the material diseases disappear. Śrīla Vyāsadeva saw the all-perfect Personality of Godhead, and in this statement the all-perfect Personality of Godhead Śrī Kṛṣṇa is clearly confirmed.
The ultimate result of devotional service is to develop genuine love for the Supreme Personality. Love is a word which is often used in relation with man and woman. And love is the only word that can be properly used to indicate the relation between Lord Kṛṣṇa and the living entities.
Loving devotional service to the Lord begins with hearing about the Lord. (from purport)
