Acharya Prashant addresses the difficulty of maintaining objectivity when investigating one's own life compared to analyzing external phenomena. He explains that while it is easy to be objective in a laboratory or with technology because there is no personal attachment, internal investigation often becomes a messy affair due to personal biases and the involvement of the subject. He introduces the concept that true detachment is actually a product of self-love. If one truly loves themselves, they will want to understand their internal state neutrally and without prejudice to escape suffering and mediocrity.
