Acharya Prashant discusses the historical and psychological aspects of Diwali, noting that while it historically relates to farmers celebrating their harvest, it has psychologically become a means for people to indulge in consumption under the guise of religion. He explains that most people are driven by a desire for pleasure and use festivals to provide a legal and moral cover for their greed. While the return of Shri Ram to Ayodhya is the central theme in North India, the speaker points out that during the shopping and festivities, the actual ideals and memory of Shri Ram are often entirely absent from people's minds.
