Cloudy winter-like days.
This is the time of year when you learn degrees, grades of darkness. You awake to a kind of dull darkness, there are patches of light, or a faint lightness seeping around the edges, but the dullness predominates. Later in the day, it may lighten up a bit, but not for long, a deeper darkness descends. Think pitch-black dark. These are days you learn about darkness.
The light comes from inside. What you know. What you think. What you decide to do. There are the beliefs, the dreams, the wonders you carry inside. There's an "inner light," illumination, a flame, or a flash-point in your solar plexus.
Darkness & Light. They are always dancing. Inside. Outside.
