When we look at life and the process of its development either from a mystical or from a scientific point of view, we shall find that it is one life developing itself through different phases. In other words, there is one vital substance -- call it energy, intelligence, force or light, call it God or Spirit -- which is forcing its way out from the most dense aspect of nature towards the finest aspect of nature. For instance, by studying the mineral kingdom we shall find a life in it which is forcing its way out. When we look at it scientifically we shall find that from the mineral kingdom come substances such as gold and silver and precious stones, which means that there is a process by which the mineral becomes finer, finer and finer, until it begins to show that the spirit is radiance, intelligence, beauty, and that it even manifests through the precious stones.
