Acharya Prashant clarifies the distinction between concentration and attention, asserting that concentration is generally a barrier to attention because it is rooted in the ego and driven by personal interest. While concentration requires a doer who exerts effort and experiences tension, attention is characterized by the absence of a doer and a state of complete relaxation. Concentration is always directed toward specific objects based on an individual's desires and history, leading to a fragmented mind and internal conflict. In contrast, attention leads to a singular silence that is universal and beyond the mind's various colors.
