Jupiter stations direct today (March 6th) at 10 degrees Cancer.
Back on November 7th, 2013 (when Jupiter went Rx) expansion in the Cancer area of your chart shifted, slowed or stopped. It was break time; the big inhale. Since then, you've had a few months to mull over opportunities, or do some internal evaluation on what increased in your life.
Now, it's time to exhale. Move forward with your opportunities, express your needs/emotions fully, or move on (and up). Jupiter is also about freedom, and can sometimes trigger release from a limiting situation. Watch for something that you thought was over/impossible to surge forward again.
Jupiter does not always bring blessings. It can make anything bigger, and sometimes that includes difficulties. So Jupiter direct may stir up emotional squalls that went dormant in November. It's still Jupiter though, and I've found that no matter what it increases, this planet always brings opportunity in the guise of release and exploration. What lies beyond your immediate circumstances (whether they are positive or negative) is where Jupiter's silver lining is.
10 to 20 degrees Cancer (the Rx degrees) will be emphasized, and Jupiter will be hitting them again as it moves forward. Pay attention if you have planets/angles/Nodes (natal or Progressed) within these degrees. But anyone can take advantage of this transit by pushing the potential of the natal house that Jupiter is moving through.
This influence complements Venus' move into forward-looking Aquarius. Basically, Aquarius and Cancer are the signs where you'll experience opportunity, growth, movement and attraction.
