Kamalini: One time Srila Prabhupada was asked in a challenging way, "Since you're the guru and you know everything, how many windows are in the Empire State Building?" Srila Prabhupada replied, "How much water is in a mirage?" How brilliant because what's the significance of how many windows are in the Empire State Building? It is as significant as how much water is in a mirage. Both are meaningless. From that response I realized we need to ask the guru only relevant questions.
