Here we are, at the final full moon of 2021. This Gemini Full Moon will occur at 27° and is bookended by the ancient festival of Saturnalia and Yule, the Winter Solstice. If we were to look at the entire year and think of it as a lunar cycle, or lunation, the Winter Solstice would be the New Moon of the year.
This New Moon begins the Lunation of the Lessons of Truth. The Gemini/Sagittarius axis is the Axis of Truth in Navigational Astrology and encompasses all things on that spectrum from the truth being slippery to the truth being a righteous crusade to the truth being the ultimate TRUTH of truths.
