We can say that if we are wise, we can see beyond material things. What we then see can is the truth. The world is in a muddle now because people don’t use their eye of Wisdom to see things. People are distracted and deluded by greed, hatred and ignorance. These desires mix them up, or bring them down and then lead us to suffering. People become distressed, depressed, anxious and suffer. These things can be called the darkness of life. Only wisdom will lead the world out of the darkness.
