Here is an golden oldie, but still relevant. It has probably been posted before although i could not find it. But nevertheless this video with Jayadvaita Swami giving class in the ISKCON Temple London on the 13th of september 2009. The first part is a short musical intro and afterwards Maharaja speak on the Bhagavad-gita chapter 9 verse 3. The questions and answers at the end of the class are really interesting, specially the question about humility. Enjoy!
