Acharya Prashant explains that good and bad deeds are not absolute concepts but are entirely relative to the individual. He clarifies that the truth or the absolute is beyond duality, whereas humans live within the relativity of good and bad. A good deed is defined as that which takes a person beyond their limits, confinements, and ignorance, while a bad deed is that which keeps one bound. He emphasizes that instead of looking for a moralistic framework or a subject-independent answer, one must look at themselves and their own situation to understand what is truly beneficial.
