Imbolc has a powerful gift which we can put to good use throughout the year, but especially during the time which spans from Imbolc itself to the following Sabbat. While the celebration of a particular day is important, we need to be aware of what the Sabbat brings to us. And Imbolc has something which can be highly relevant.
Think of our most ancient ancestors, still learning how the world works. Some will have figured out the cycle of seasons, but there might be doom-sayers among them who claim that winter has come to stay. But when the first shoots poke up through the snow, they accepted the fact that they are seeing the fulfillment of the promise made at Samhain and repeated at Yule.
And we can harness this power to meet our needs!
