According to Forever Conscious, "The winter solstice celebrates the longest hours of darkness or the rebirth of the sun and is believed to hold a powerful energy for regeneration, renewal and self-reflection. In Pagan times the winter solstice was referred to as Yule and was a celebration of the Goddess (Moon) energy. It was believed that on this day, the moon would give birth to the sun."
That certainly puts a slightly more magickal spin on things!
The winter solstice is a time of quiet energy, where you get the opportunity to look within yourself and focus on what you want and need. It's a time to set goals and intentions for the coming year, to examine and let go of our past, and to make changes within ourselves. The solstice is essentially tied to a personal awakening.
