The Moon has two nodes -- the North and South Nodes or, alternatively, the Dragon's Head and Tail -- that are directly opposite each other. They come from a complex mathematical equation that deals with the moon’s orbit in relation to the path of the Earth around the Sun -- a lot of technical mumbo-jumbo that’s not nearly as interesting as what the Nodes represent in your life: your future and your distant past.
The North Node points to your path into the future. The lessons you need to learn in life lie within this node’s realm, which can reveal whether or not you’re living up to your full potential.
Do you feel like you’re heading in the right direction, or do you have the sense that something is off? Making life decisions based on other people’s desires or expectations of you often isn’t the best way to progress; the North Node encourages you to take charge of your own life.
The North Node is exalted when it is in Gemini.
The South Node points to your distant past, including past lives. Both of the nodes have to do with karma, and the South Node is all about the lessons you’ve carried over from your earliest upbringing or even a past life to the present.
Even if you have no memory of your early childhood or of having lived and loved before, the experiences of your deep past have left an imprint on your soul.
Any unfinished business will be carried through to the present, pushing you to learn your lesson, gain understanding and finally lay those experiences to rest.
The South Node is exalted when it is in Sagittarius.
