Acharya Prashant explains that spirituality does not require the cessation of physical or mental functions, such as breathing, thinking, or having interests. He clarifies that the brain and body are designed to have interests and relationships with the world, and renunciation should not be stretched to the absurd limit of physical self-destruction or suicide. Just as the lungs require oxygen, the intellect is naturally curious and will remain interested; spirituality is not about depriving the mind of thoughts or feelings. The real issue is not the presence of thought or emotion, but the misplaced presence of the 'I' or the little self within them. He distinguishes between necessary thought, such as solving a mathematical problem, and thought driven by fear and self-preservation. Ultimately, spirituality is about recognizing that life is beautiful without the intervention of the ego and understanding that insecurities and loneliness are imagined problems rather than inherent flaws of the mind or body.
