Pick up a stone, watch it fall from your hands. Gravity pulls it toward all the other stones. Many people still hold a special fondness for certain elements, like sitting around an open fire. Perhaps this dates back to the cave-dwellers, the primitive human Ancestors huddling around a flame merely to survive. Elementals burn deep within us, feeling that special romance in the warmth and light of a campfire, a household fire place, or even a simple votive candle.
Many people also have a special fondness for water, the ocean, from which all life on Earth arose.
Water was the source, life's birthplace. Water vapor rises from the ocean, crystallizes to form a raindrop, falls to the Earth, runs its course through life's rivers and streams, returning to the ocean, its source, to vaporize once again, perpetuating water's cycle. Even today, Pagans sing about a drop of rain flowing to the ocean, returning to its source, the source of all life. This song even tells where we come from, and reminds us that we shall return. Think about the words.
