This “low holiday” or “lesser sabbat” falls on the Winter Solstice, the longest night and shortest day, when the decreasing days give way to increasing light and life. The Goddess becomes the Great Mother and once again gives birth to the new Sun King. This sabbat is also known as Midwinter’s Eve. This date varies each year.
This is the holiday that i celebrate with "Seasons Greetings" (and i always send out cards with out the mention of Christ even though most of my friends are Christians.) I also love winter!
and i don't consider it at all low!
