Acharya Prashant responds to a question about the powers of the subconscious mind, specifically the claim of being able to read letters from a sealed envelope. He begins with a disclaimer that he has not read the book in question, 'The Power of Your Subconscious Mind,' but states that if such claims are made, they are worthless assertions. He then questions the very desire to know the contents of a letter without opening it, describing it as a 'peeping Tom' mentality. He suggests that the desire itself is a function of the desirer and needs to be examined. The speaker explains that the subconscious mind is the seat of tremendous suffering, evolutionary conditioning, and bondage. While it possesses powers, these powers serve to keep a person in bondage rather than to help them. It is the source of latent anger and fear and is what comes to the fore during sleep in the form of dreams. He clarifies that no dream can liberate you because dreams only contain what you are already composed of. True liberation cannot come from within the 'jail' of the mind; it requires breaking out through transcendence. He further elaborates that what one thinks they do consciously is often coming from the subconscious mind. Therefore, by observing one's life, actions, and choices, one can understand the contents of the subconscious. He notes that since our lives are often not pretty, it indicates that the subconscious does not hold pretty things. He posits that civilization, culture, and education are attempts to cover up the 'ugliness' contained in the 'basement of the subconscious,' which he describes as wild, suffering, and insane. In conclusion, Acharya Prashant advises against looking for powers or solutions in the subconscious, which he calls the 'place of your disease.' Instead, the conscious mind should be used to bring the darkness of the subconscious to light. He asserts that real power lies not in the conscious or subconscious mind, but in freedom from the mind, which can be called pure consciousness or superconsciousness. The power of the subconscious is the power of the ego, an enemy, not a friend. The way to know and ultimately liberate the subconscious is to be more attentive and sensitive to one's daily life, thoughts, and actions.
