Looking into your body, you will discover that you are not a separate self, cut off from everything else, but that you are a continuously flowing stream—the stream of life itself. The one contains the all. Your body can tell you everything there is to know about the cosmos, boundless space, and time without end. You will see that the here is also the there, and that the now carries within itself the span of eternity, including the past and the future. Eternity is there to be touched in each moment. Both sun and moon, all the stars and all the black holes, can nestle comfortably inside a tiny grain of sand.
