Acharya Prashant explains that the growing crisis of anxiety and mental health issues among teenagers is not a sudden development but the result of years of conditioning. From a young age, children are taught that the world is everything, leading them to believe that their internal state should be governed by external circumstances. This creates a conflict because the human heart naturally seeks stability and serenity, while the world is inherently fickle and unpredictable. When the world is allowed to penetrate the heart, it leads to stress and anxiety because the individual's self-worth becomes dependent on external validation, such as peer approval or material possessions.
