Acharya Prashant explains the nature of worry by referencing the teachings of Kabir Saheb, who describes worry as a demoness that consumes one from within. He emphasizes that worry is a mental phenomenon and cannot be cured by external or material means. A physician can treat the body, but since worry resides in the mind, external remedies like money, prestige, or relationships are ineffective. Even if an external cause of worry is removed, a restless mind will quickly find a new object or reason to remain anxious. The speaker asserts that worry does not actually have a valid cause; it is simply a state of a disturbed mind that seeks excuses to remain in turmoil. He further explains that the mind thrives on disturbance and is afraid of silence or peace. People often seek distractions, such as loud music or unnecessary talk, because they are uncomfortable with stillness. Acharya Prashant suggests that the best way to avoid worry is to remain fully engaged in meaningful work. When the mind is completely occupied with the task at hand, there is no space for the imagination to create fearful scenarios. He warns against trying to solve internal mental conflicts through external actions, stating that since the problem is internal, the solution must also be internal. One must recognize the mind's tendency to create trouble and not get carried away by its restless thoughts, desires, or plans.
