“We may be very proud of our eyes, but we cannot even see our next-door neighbor. People challenge, ‘Can you show me God?’ But what can they see? What is the value of their eyes? God is not cheap. We cannot see anything, not to speak of God, without sunshine. Without sunlight we are blind. At night, we cannot see anything, and therefore we use electricity because the sun is not present.” (Shrila Prabhupada, Easy Journey To Other Planets, Ch 2)
