Acharya Prashant clarifies that the witness or pure observer cannot be witnessed or sensed as an object because all human perception is dualistic and limited to finite objects. If something is truly infinite and always present, it cannot have boundaries or be perceived from a distance. He explains that the repetition of "I am Brahman" mentioned in scriptures is not a mere verbal or mental pattern, but a way of living. True repetition means living in an unfettered way, free from the chains of habit, sorrow, and insecurity, even amidst the rigors of daily life. Creating a mental pattern out of repetition may only suppress existing patterns rather than dissolving them.
