All experience involves two factors - experiencer & experienced, observer & observed, subject & object. As such, all experience is inherently dualistic. So then, how is it possible to experience nonduality?
The sages of ancient India, the rishis, taught that nonduality is not a property of any object experienced. Instead, it is a property of the experiencer, the awareful subject, the conscious observer. They discovered that pure consciousness, the essential nature of every sentient being, is indeed a nondual fundamental reality. So the nondual nature of atma, your true self, can be be figuratively "experienced" only as one's own conscious nature, since consciousness is present in every experience,
Like you cannot objectify or experience nonduality; you cannot meditate on it either. Yet, meditation can be used to validate or confirm what the ancient rishis discovered - that the nature of consciousness is nondual. How? In samadhi, when your mind is perfectly still, completely silent, all that remains is nondual consciousness, advaya atma. If any dualistic object happened to remain in samadhi, you would experience it. But all dualistic experience is absent in samadhi.
To discover what the rishis discovered, you do not need to be a master meditator. You only need to be capable of producing a few moments of perfect silence. In the guided meditation part of this class, Swami Tadatmananda teaches a simple but powerful technique for producing a few moments of silence, and those few moments are enough for you to personally confirm what the rishis discovered.
