Vidura explained to Maitreya his position of being fully satiated with the knowledge of mundane social and political topics and having no more interest in them. He was anxious to hear transcendental topics regarding Lord Sri Krsna. Because there were insufficient topics directly concerning Krsna in the Puranas, Mahabharata, etc., he was not satisfied and wanted to know more about Krsna. Krsna-katha, or topics regarding Krsna, are transcendental, and there is no satiation in hearing such topics. Bhagavad-gita is important on account of its being krsna-katha, or speeches delivered by Lord Krsna. The story of the Battle of Kuruksetra may be interesting for the mass of people, but to a person like Vidura, who is highly advanced in devotional service, only krsna-katha and that which is dovetailed with krsna-katha is interesting. Vidura wanted to hear of everything from Maitreya, and so he inquired from him, but he desired that all the topics be in relationship with Krsna. As fire is never satisfied in its consumption of firewood, so a pure devotee of the Lord never hears enough about Krsna. Historical events and other narrations concerning social and political incidents all become transcendental as soon as they are in relationship with Krsna. That is the way to transform mundane things into spiritual identity. The whole world can be transformed into Vaikuntha if all worldly activities are dovetailed with krsna-katha.

There are two important krsna-kathas current in the worldBhagavad-gita and Srimad-Bhagavatam. Bhagavad-gita is krsna-katha because it is spoken by Krsna, whereas Srimad-Bhagavatam is krsna-katha because it narrates about Krsna. Lord Caitanya advised all His disciples to preach krsna-katha all over the world without discrimination because the transcendental value of krsna-katha can purify one and all from material contamination.
