Acharya Prashant addresses the misconception regarding 'inside' and 'outside' in the context of self-inquiry and introversion. He challenges the notion that the mind is 'inside' simply because it is contained within the skull or skin. He posits that whatever can be observed, touched, or understood is fundamentally an object of understanding and, therefore, external to the observer. Since the mind and its processes can be observed, they are as external as the physical world. He uses the analogy of an onion to explain that peeling away layers of personality—which are all acquired from external influences like family and society—eventually leads to a state of 'no layer,' which represents the true self or the intelligence that understands.
