Acharya Prashant explains that Vedanta is not a philosophy in the traditional Western sense but is fundamentally an inquiry into one's own nature and the nature of the mind. He describes it as a process of questioning why we feel unfulfilled and who we are, starting from the certainty that we are not currently content with ourselves. Because the ego's current situation is unique to every individual, age, and community, the same core truth must be presented in various ways by different sages and teachers. He emphasizes that the ego has a tendency to co-opt spiritual words to reinforce itself, necessitating a continuous tradition of teachers who must re-interpret the truth to checkmate the ego's latest distortions.
