Acharya Prashant responds to a question about whether it is more important to know what to do or what not to do. He explains that both doing and not doing are functions of the doer. Therefore, the primary question is not about the action but about the doer itself. He uses the analogy of an instrument or a gadget, like a Life Positioning System (LPS). Instead of asking whether the instruction to go left or right is more important, one must first question if the instrument itself is trustworthy. If the inner machine is not right, its output will be wrong. Any correct output from a faulty machine is merely a fluke and not repeatable. The speaker points out that the job of an engineer, like the questioner, is to investigate the inner machine. He states that most people have an inner list of 'do's' and 'don'ts' that they follow, but these lists are not their own; they are a product of conditioning based on factors like nationality, gender, or religion. People are often very sure about their life choices, such as career paths or personal decisions, without ever investigating where these certainties come from. This 'doership' arises from conditioned instincts. Ultimately, Acharya Prashant emphasizes that the so-called inner voice or conscience is often artificial and influenced by external factors, making it an 'outer' voice. He says that wisdom lies in realizing that this conscience is 100% influenced. The crucial questions a young, intelligent person must ask are about the doer: Who is the doer? What does he want to achieve through the deed? Where do his thoughts and emotions arise from? It is not about just doing something, but about knowing the doer, knowing what you lack, and what you need to shed. Once this self-knowledge is attained, the deed will be right, and you will know the one right direction for you, unambiguously and choicelessly.
