About the Waning Moon
Third Quarter: (day after the full moon until the waning half moon) As the moon wanes, the focus begins to turn within. Pay attention to your inner voice-your instincts and gut hunches. This is not the time to ignore that inner monologue. You may find that you are “hearing between the lines,” meaning you are hearing or sensing what is unspoken, so think before you speak. Ride the back of this wave of lunar energy and realize that the energies around you can be used to your benefit. Tune in to your own spirit and meditate. Work with divinatory tools now to see what is hidden from you.
