There are unlimited benefits of organizing and attending at Srimad Bhagavatam Katha. The prime result is that if a person is hearing attentively can attain pure love for Krishna. There are many benefits and we will mention a few described in Srimad Bhagavatam Mahatmya of Skanda Purana.
The Supreme Lord said: O Grandfather Brahma, one should regularly hear the famous Srimad Bhagavatam with faith. Know for certain that such hearing is the only means of satisfying Me. One who daily reads Srimad Bhagavatam will attain with every syllable the results of giving a brown cow in charity. One who daily reads or hears even a half or a quarter of a verse of Srimad Bhagavatam attains the results of giving one thousand cows in charity.
