Both gods are honored during this time by bringing an evergreen indoors and decorating it with light and colorful ornaments that represent the abundance of the coming spring like birds, fruit, and flowers, along with those that symbolize rain like icicles. Gift-giving is also an ancient tradition, although in past times these were mostly handmade gifts from the heart.
I think we lose sight of the true meaning of this time because we sit in our heated homes lit with electricity during these shorter, colder days. We also grab our food from the grocery store shelves instead of having to rely on weather conditions to grow our own. It must have been frightening for people who had a lack of scientific knowledge to grasp on to the idea that spring and summer would return, especially when their food stores and fire fuel started to run low. This truly is a magical time when the shorter days start to lengthen and warmth and sunshine returns.
Merry Christmas and Happy Yule.
