Acharya Prashant explains that silence itself has no utility or meaning for us; it is the expressions or 'utterances' of silence that are significant. He clarifies that while silence is invaluable and represents the ultimate reality, one should not attempt to meditate on or desire it directly. Just as a building's foundation is essential but remains unseen, truth is the foundation of existence that should remain unmanifest. He advises against the common spiritual mistake of trying to bring the unmanifest truth into the manifest realm, suggesting instead that we should focus on what is visible and present, like a flower rather than digging for its roots.
