"In a real deep laughter the mind disappears. It is not a part of mind or of the heart. When a real laughter happens -- a belly laughter, as it is called -- then it comes from your very core; from your very center ripples start spreading towards your circumference. Just as you throw a rock into a silent lake and ripples arise and they start moving towards the source, in the same way real laughter arises from your center and moves towards your circumference. It is almost like an earthquake! Each single cell of your body, each fiber dances in tune."
