…even a person perpetually condemned to the miseries of material existence can get relief from bondage if he simply agrees to hear only krsna-katha. In this age of Kali, the process of hearing krsna-katha is the most effective means to gain release from unwanted family affection and thus find permanent freedom in life. The age of Kali is full of sinful reactions, and people are more and more addicted to the qualities of this age, but simply by hearing and chanting of krsna-katha one is sure to go back to Godhead. Therefore, people should be trained to hear only krsna-katha — by all means — in order to get relief from all miseries.
