Void Moons happen when the Moon doesn't have any connection (aspect) to another planet until she enters the next sign.
In that space, exiting one sign and leaving behind all her past aspects, she is isolated.
Alone. Disconnected.
The Moon reflects how we, as humanity, are connected to the energies of the world. She is our collective emotional flow, and Void Moons are moments when we have no way to connect to anything. It's a break, a pause, a void moment. Bathing in aether.
