Acharya Prashant explains that truth has a transformative effect on an individual, often making the eloquent silent, the clever simple, and the energetic restful. He notes that those who prioritize worldly happiness often avoid the truth because it reveals the foolishness of their words and the futility of their cleverness. In the eyes of the world, this transformation is often mislabeled as stupidity or laziness, but it is actually a state of innocence and rest. The speaker emphasizes that spiritual realization makes a person 'useless' to a society that wants to exploit them as a 'useful slave,' leading to social disapproval or even hatred toward spiritual teachings.
