Certainty undermines one's power. There is nothing in your life that will not change, especially your ideas of God. look what the insanity of righteous knowledge can do: Maim thousands in wanting to convert that which is already gold into gold. Certainty can become an illness that creates hate and greed. God once said to Tuka: ‘Even I am ever changing; I am ever beyond myself. What I may have once put my seal upon, may no longer be the greatest truth.'
