Acharya Prashant explains that a person's life is often spent relying on words, which represent material objects and mental images. When one realizes that they have been immersed in the unreal, a natural silence follows because speaking further would only reinforce the false as truth. He illustrates this with the story of the Buddha, who initially hesitated to speak after enlightenment until persuaded that his words could guide those standing on the edge of realization. He emphasizes that the testimony of scriptures and gurus is unique and essential, as the worldly perspective will never offer the same truth.
