Acharya Prashant explains that the Bhagavad Gita remains immortal because humans continue to be trapped in their emotions, past, and ego, much like Arjun. He clarifies that duality is not separate from the truth; rather, it is the truth in a shrouded or divided form. While everything that exists proceeds from the truth, not everything is useful for an individual's well-being. He suggests that instead of claiming to be a seeker of truth, one should be a seeker of relief from suffering, as the truth is already present but often experienced in a troubled state.
