How can a man grasp the inner world with landscapes colored by nothing seen by the human eye? A baby in the womb would call you a liar if you told him there are mountains, streams, blue skies, and green grass with four legged animals walking on land; and even more wonders in the sea. The baby would dismiss your flights of fancy and deem you mad. A blind man is content with his state and does not wish to attain to higher spiritual grades.
