Acharya Prashant explains that the concept of fate or destiny (bhagya) does not imply a pre-written script or a divine entity controlling human lives. Instead, fate represents the infinite, unknown, and unpredictable forces of a vast system where every small action can trigger a chain of events with far-reaching consequences. He uses the analogy of a butterfly flapping its wings in Japan causing an earthquake in America, or a single person's actions leading to a global pandemic, to illustrate this inherent randomness and unpredictability of the material world. This unpredictability is what humans label as fate because its root causes are impossible to calculate or fully understand.
