Acharya Prashant explains that all words, thoughts, and concepts are mental constructs that lack independence because they depend on each other for definition. At the center of this mental activity is the false 'I' sense, which is a product of sensory experience, physical processes, and time. Because thought is existentially tied to this false 'I', it functions like a tethered animal; it can move endlessly in circles but can never violate or uproot its own center. Consequently, thought exists to serve the ego rather than expose its falseness, making it an ineffective tool for reaching the truth or achieving liberation.
