Acharya Prashant explains that a small child gets corrupted because their innocence lacks the protection of worldly knowledge. He emphasizes that knowing the ways of the world is equivalent to knowing oneself, as it allows one to understand the operations of Maya. He notes that saints were able to reform society precisely because they understood its inner workings and drawbacks. Without this understanding, worldly influences inevitably affect an individual. He warns that as long as one possesses a body, the tendency to be conditioned remains, meaning spiritual evolution is not irreversible and requires constant vigilance. Using the story of a painter who found the same person to be the model for both the most innocent and the most vile face over twenty years, Acharya Prashant illustrates how easily human purity can be corrupted by time and influence. He describes knowledge as a double-edged sword: it can be a staining burden or a protective armor. For those not guided by scriptures or teachers, knowledge is often a useless weight or a source of bondage, such as being addicted to trivial news or gossip that adds no richness to life. He criticizes modern media for using news to induce artificial desires and manipulate people into becoming consumers. Ultimately, Acharya Prashant clarifies the seemingly contradictory role of a Guru. A teacher first advises a seeker to drop all accumulated, poisonous knowledge to clean the consciousness. However, once cleaned, the seeker is advised to adopt the right kind of knowledge as an armor to prevent future corruption. He compares this to understanding how a virus operates to defend against it. He concludes that spirituality is too subtle for those who rely on simple slogans, and that one must possess the right knowledge to navigate and protect oneself from the world's manipulations.
