Acharya Prashant explains that real understanding is neither personal nor universal; in fact, true understanding results in the disappearance of the issue itself. When something is truly understood, it becomes meaningless and irrelevant, vanishing from the mind. He introduces the term 'understander' to describe one who has gone beyond themselves. He clarifies that what is commonly called understanding is often just intellectual comprehension or a movement of concepts within the same dimension, whereas a true knower sees that nothing fundamentally changes on the surface of reality.
