Acharya Prashant explains that the past is not inherently harmful; it becomes problematic only when one retreats into it to escape a foul or unbearable present. He clarifies that memories and past experiences are valuable resources, much like knowledge or money, which can be used to enrich and beautify the present. He dismisses the notion that liberation requires forgetting the past, noting that if memory loss were the key to enlightenment, those suffering from amnesia would be liberated. Liberation is a grand endeavor that requires utilizing all available resources, including the past, rather than fearing it or making it the center of one's life.
