Acharya Prashant explains that real inquiry is not about asking questions like 'what is fan' or 'what is freedom,' because such questions assume that freedom exists in the same dimension as physical objects. By asking 'what is,' a person limits the scope of the answer to their own existing dimension. He clarifies that while inquiry at a railway station involves asking questions, in life, real inquiry happens in silence and through attentive listening. He uses the metaphor of a hollow flute to describe emptiness, suggesting that one should let experiences pass through without retaining or being corrupted by them, thereby maintaining childlike innocence despite having seen the world.
