Acharya Prashant explains that anything that takes an individual away from their peace is inherently wrong. While certain things like drugs generally destroy one's ability to think and are considered bad in most cases, there is no universal definition of virtue or vice. He clarifies that the ultimate definition of virtue is that which brings one closer to their true nature, while vice is that which takes one away from it. He distinguishes between nature and habits, stating that while personalities, conditioning, and circumstances differ among people, their fundamental nature is the same, characterized by silence and emptiness. He emphasizes that conditioning, or 'Sanskara', is neither good nor bad but is simply external influence; the ideal state is to be free of all conditioning. This state of emptiness is not a lonely void but a vibrant, beautiful, and complete fullness. Addressing the question of living without reasons for joy or sorrow, he advises observing one's current state of being rather than imagining a life without them.
