Srila Prabhupada gives a lecture on the universal principles found across religions and scriptures. He explains that the main aim of all faiths is to achieve liberation from the material world and return to the spiritual realm. While practices may differ slightly based on culture or situation, the core message is the same - to realize our eternal relationship with God. Prabhupada uses examples from the Bhagavad Gita to elucidate what true knowledge is - understanding our constitutional position as an eternal servant of Krishna and surrendering to Him.
