Dear Reader,
We're marching our way through the Dark Season of the Year here in the Northern Hemisphere. The days draw shorter and the nights extend longer. On top of that, in my region, the weather tends more towards cloudy and cold. We haven't had our first real snowfall yet, but I can feel it in my arthritic bones that it's going to happen soon. Some questions that come up when it comes to divination is when is the best time of year to do a deep reading on issues like past lives, ancestor contact, and looking into future events.
Folk wisdom in the Pagan community at large says that during the Dark period (be it of the Moon or Sun) is the best time to look into hidden things. The premise is just as the source of light is hidden, so is the details of the matter that you are reading on. It goes back to the principle of "like calls to like," which is one of the fundamental concepts of modern magical practices at large. In my experience, deep readings can be done in either season, the question is what is your focus.
In the Light season, your focus would be casting light upon the hidden details. This will reveal different information (sometimes more superficial information) than what you would get during the Dark season. The Dark season is the time for the focus to be on summoning the hidden details to reveal themselves to you. You are not casting light upon them as much as raising them from the depths as you would raise the dead from where they lie.
The information gleaned from the Dark season readings is going to tend towards brutal honesty and a hard push towards confronting your Shadow Self. I'm not saying that information from Light season readings are not going to push towards that as well, but Dark season readings are going to push far harder in that direction.
