Acharya Prashant emphasizes the importance of deep investigation into things we assume to be obvious. He explains that we are most likely to be deceived in matters where we believe we already possess the truth. While we remain alert regarding things we find suspicious, we often fail to question everyday concepts like education, development, mind, and personality. He asserts that most people use these terms daily without truly understanding their essence, relying instead on groundless assumptions. He warns that assuming makes both parties ignorant, as it replaces reality with false perceptions. Using the example of friendship, Acharya Prashant challenges the common understanding of a friend as someone who merely helps in times of need or supports one's actions. He references Shri Krishna and Arjun in the Mahabharata, noting that Shri Krishna, as a true friend, urged Arjun to fight his own kin for the sake of righteousness, rather than offering false comfort. He explains that to recognize a wise friend, one must first become wise themselves. An ignorant person will naturally gravitate toward other ignorant people, as darkness cannot befriend light. He concludes by advising students to use their college years to develop intelligence and energy rather than just collecting degrees, urging them to observe their surroundings and relationships with clarity to avoid living in deception.
