Does the realised being tell you that the world is full of pain? It is the other one who feels the pain and seeks the help of the wise saying that the world is painful. Then the wise one explains from his experience that if one withdraws within the Self there is an end of pain. The pain is felt so long as the object is different from oneself. But when the Self is found to be an undivided whole who and what is there to feel? The realised mind is the Holy Spirit and the other mind is the home of the devil. For the realised being this is the Kingdom of Heaven. "The Kingdom of Heaven is within you." That Kingdom is here and now.
