Acharya Prashant explains the three methods mentioned in the Upanishads to realize the Self: reasoning (Yukti), listening (Shruti), and self-experience (Svanubhuti). He defines reasoning as the process of questioning, demanding proof, and using logic to expose falsehood. He emphasizes that while logic may not reach the ultimate truth, it is essential for dismantling superstitions and lies. He clarifies that spirituality is not against science; science studies the object (the pendulum), while spirituality studies the subject (the observer of the pendulum). True faith (Shraddha) is not blind; it is the state of non-opposition that remains after all logical inquiries and experiments have been exhausted. Regarding listening (Shruti), Acharya Prashant distinguishes between listening to maintain one's internal lies and listening with a clean intention to find the truth. He notes that a person living in falsehood often avoids certain topics because the truth is a threat to their ego. Shruti refers to listening to words that cut through illusions and lead toward the truth. It is the first step toward Samadhi, provided one has the discernment to choose what is worth hearing. He suggests that the presence of truth acts as a filter, as those who are dishonest will naturally flee from truthful discourse. Finally, he discusses self-experience (Svanubhuti), clarifying that mere worldly experience does not lead to liberation; otherwise, everyone would become enlightened with age. Instead, Svanubhuti means observing the 'experiencer' (the ego or 'Aham') behind every experience. He explains that while an external event is the same for everyone, the internal experience varies based on the individual's mental state. By investigating the root of one's reactions and experiences, one understands the ego. Realizing the nature of the ego is the only way to be free from it, which is synonymous with attaining the Self.
