Acharya Prashant explains that life is characterized by constant change, which can be perceived as either good or bad. He emphasizes that stress arises only when one forgets the transient nature of these changes and begins to view them as permanent. When a person fails to recognize that a situation is temporary, they become trapped in emotional turmoil, leading to extreme reactions such as suicide over failed relationships or academic failure, or violence during moments of anger. He asserts that if one truly understands that everything in the world is in a state of flux, like images on a cinema screen, one cannot take these events with absolute seriousness.
