Acharya Prashant explains that restlessness is a deep-seated mental state that serves as the foundation for all human decisions, thoughts, and perceptions. He argues that changing one's external environment, such as moving from one city to another, does not resolve internal restlessness because the individual carries their mental state wherever they go. Even in a serene location, a restless person perceives the world through the lens of their own dissatisfaction. He emphasizes that seeking pleasure through external means like substances or travel is often a reaction to underlying pain, and identifying with that suffering only perpetuates the cycle of seeking relief without addressing the root cause.
