" Sensei would be far more unhappy without me. Why, he might not even want to go on living, without me. It may seem very conceited of me, but I do really believe that I am able to make him as happy as is humanly possible. I believe that no one else would be able to make him as happy as I can. Without this belief I would not be as contented as I am "
