Before that a person attaches too much importance to his joys, to his sorrows. If he is sad, the whole world is full of sadness. If he is a little joyful, the whole world is full of joy. As if the sun rises and sets by his joy and sadness. But indifference must be reached after interest has taken its course. Before that it is a fault. A person becomes exclusive, he becomes disagreeable, without interest in life. It must come after all experience. Interest must end in indifference. He must not take the endless path of interest; the taste of everything in the world becomes flat. Then he realizes that all that we seek in all the objects we run after, all beauty and strength is in himself, and he is content to feel all in himself. This may be called the kiss of the cross. Then his only principle is love.
