Whether this particular day marks for you a simple celestial event unique to our solar neighborhood, or a sacred quarterpost within the wheel of the year, it remains unarguable that something special is happening right now.
We in the northern hemisphere experience the longest day (in terms of daylight hours) of the year. Our friends in the south experience the shortest. In either case the day culminates a pattern of the season that’s been building, that now stands still, that next begins to subtly shift the other way.
It’s orbital mechanics, the tilt of the poles. And it’s magick. It’s both.
The dichotomy doesn’t matter. What matters is that the seasons change, and we change. And it could just be that we’ve never needed that more.
