Acharya Prashant explains that consciousness is the fundamental sense of 'I am' and the awareness of the world, characterized by the duality of subject and object. He describes the first stage of consciousness as fear, which arises from the perceived separation between the self and the vast, uncontrollable world. This fear underlies all human emotions, including attraction and attachment, because everything in the material world is subject to time, decay, and change. To escape this fear, consciousness seeks security through compromises, often settling for the most powerful available option or substitute, which leads to a cycle of endless seeking and dissatisfaction.
