A questioner expresses confusion about the nature of experience, particularly the experience of peace. He mentions being taught that any experience is duality (dvaita), and non-duality (advaita) is without experience. He recounts visiting various meditation centers where practices like smelling smoke from a pot or engaging in kirtan led to a feeling of peace, which was described as a taste of non-duality. He questions this, asking how these experiences can be non-dual if they are felt, and also inquires about claims of people meditating for days without awareness of time, wondering if that is a non-dual experience. Acharya Prashant clarifies that there are two types of peace: dualistic and non-dualistic. Dualistic peace is merely an experience that depends on its opposite. He provides examples, such as the relief felt from eating after being hungry all day, or the comfort of removing tight pants. This type of peace is just a reduction in restlessness and is a cheap, temporary relief that often leads to the next form of tension. The methods used in some meditation centers provide this dualistic peace. In contrast, non-dualistic peace is like being in the eye of a cyclone; while restlessness and the movements of life continue externally, one remains still and untouched at the center. The proof of this inner peace is the ability to stop any external action or emotion at will. For instance, one can pause in the middle of an argument to smile and then resume, indicating that one is not controlled by nature (Prakriti) but is merely acting within it. This is the real peace, which is a state of being, not an experience. Acharya Prashant further explains the difference between the teachings of life and a Guru. Life teaches through the harsh principle of karma, often breaking a person without compassion. A Guru, however, teaches with compassion. Using the questioner's analogy of an air hostess, he says a Guru can show you the consequences of your actions and save you from them, much like the air hostess who could take the child off the plane and then put him back. Life, however, would simply eject you. This opportunity to learn from a Guru is rare and should be valued.
