A really mature person cannot be serious, there is nothing to be serious about. The whole of life is fun, it is a play, a play of consciousness. And that's what meditation reveals to you - that the whole of life is a beautiful play of energy. The same energy is in the trees, in the stars, in the rivers, in the mountains, in you, in animals. It is the same energy dancing in different forms. We in the East have called it 'Leela'. Leela means God's play. - Osho.
