Is Scorpio in the spotlight, or what? Not only will Saturn be entering this sign, but so will the transiting North Node (on August 29th).
The North and South Nodes are mathematical points (not planets). Here's the technical stuff if you want to know how they're calculated. They describe past life situations that color habits (South Node) in this life, and the path you take to evolve forward and reach your full potential (North Node). The Nodes have transits, just like planets. They will be moving from 0 degrees Sagittarius (North Node) and 0 degrees Gemini (South Node) to 29 degrees Scorpio (North Node) and 29 degrees Taurus (South Node).
Initiating and developing unfamiliar (but progressive) talents/situations/relationships will be triggered by the North Node's transit of whatever house has Scorpio in your chart. Since we're talking Scorpio, expect to push (or be pushed) through limits to get to these new energies. You'll have to go deeper and be authentic. It will be your evolutionary prompt.
If the transiting North Node passes over a planet, add the planet's energy to the mix. For example, the North Node passing over Mercury in your 10th House could push you to communicate in a more authentic/strategic way (in your career). Or it could introduce a person who provokes you, on the job, thereby deepening your awareness of what you're capable of.
Moving past ingrained/stagnant behaviours is the theme of the transiting South Node. This will be directly opposite the transiting North Node. For whatever is being initiated in your Scorpio house, there will be a corresponding situation/behaviour in the opposite house that you need break away from. It will involve Taurus energy, so think about moving beyond your comfort zone and familiar routines.
In a nutshell, the transiting Nodes are evolutionary triggers that are coloured by the sign and house they pass through. This Nodal transit will involve launching yourself from cautious (Taurus) to fearless (Scorpio).
The Nodes will transit Scorpio/Taurus until February, 2014. Then they will move into Libra/Aries.
