Acharya Prashant explains that the Bhagavad Gita contains the entire essence of Vedanta and is far more significant than the physical events of the Mahabharata war. He discusses the teachings of Guru Nanak Dev, specifically the phrase suggesting that even if one maintains constant silence or enters deep internal absorption, true peace and the Ultimate remain unattainable through personal effort. This causes distress to the ego, which believes it can achieve spiritual goals through methods, techniques, or sheer willpower, much like it achieves worldly success or scientific advancements.
