Acharya Prashant addresses the dilemma of how long one should attempt to explain the truth to someone who is resistant. Using the analogy of a burning building, he explains that while one should initially try to help everyone, if a person continuously resists and argues without reason, it is better to move on and help others who are willing to listen. He emphasizes that arguing with someone who is merely making declarations to prove themselves right is a waste of time and energy. When a person is determined to justify their wrong actions through illogical arguments, it is best to acknowledge their stance and step away, as even Shri Krishna could not save those who refused to listen.
