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, who is the one making the choice. He uses the analogy of an instrument, questioning whether one should trust its output—like an instruction to go left or right—without first verifying if the instrument itself is trustworthy. The fundamental inquiry, he suggests, should not be about the action but about the actor, the doer. The speaker emphasizes that the doer is the instrument, and the primary question must be about its reliability. He asks who the inner decision-maker is and where the options presented to us come from. He points out that while most people don't truly know what to do, they operate with great certainty based on conditioned instincts. This certainty about life choices—like career, marriage, or family—is often a product of external influences such as nationality, religion, and social conditioning. Acharya Prashant argues that the internal list of "do's and don'ts" is generated by a self that has been corrupted by alien influences and is not authentically you. He describes the commonly cited "inner voice" or "conscience" as an artificial construct, entirely influenced by the external world and varying from person to person. He notes that people have committed terrible acts while following their conscience. Therefore, the crucial task is not to choose between actions but to investigate the doer itself. Instead of focusing on the deed, one must know the doer. The essential questions to ask are: "Who am I? What do I lack? What do I need to shed?" When the doer is right, the subsequent deed will also be right. The focus must shift from the random motion of doing something to knowing the doer. It is about understanding why there must be movement at all. Once you know the one right direction for yourself, the choice becomes unambiguous and choiceless.
