Acharya Prashant explains that the purpose of life is not something external or abstract, but is deeply rooted in one's lived experience from moment to moment. He suggests that instead of pursuing grand ideals like universal brotherhood while suffering in the present, one must look honestly at their current troubles. The true purpose of life is to identify and overcome the core suffering or central limitation that keeps a person small and bound. He emphasizes that human desires are essentially attempts to challenge limits, and freedom from these bondages is our essential nature. One must move beyond superficial problems to find the 'mother problem' and target it directly.
