But if your eyes are bad, you are not able to see things well. And if that continues, the time will come when you will not be able to see at all. You will be in complete darkness [MET]. Similarly, if you continue to be greedy, you will be in spiritual darkness. If all that your eyes can see and your mind can think about involves your greedily desiring material possessions, all that you do will be evil [MET].”
