The trees are showing us their fall colors as they change in preparation for the winter. Autumn is here and the leaves are beginning to fall. For thousands of years human beings have celebrated this wonderful season of change. The pumpkin patches are full and you can get a pumpkin spice latte just about anywhere. Fall symbolically represents the ending of a particular cycle. It is also a time when we celebrate Halloween. Have you ever wondered where the idea of Halloween came from? Why do children trick-or-treat? Is it a spiritual holiday? What does it have to do with ghosts and spirits?
