According to Sandy

Saturn will finally reach Libra again on 7/21/10. This planet went retrograde into Virgo in January and reversed course in May. It has inched its way forward back into the 7^th sign of the Zodiac.

Discovered in 1610 by Galileo, I think of Saturn sometimes as the Castor Oil of the planet world.  Ancient Astrologers considered it a malefic, but recently, a more  positive spin, such as a bringer of life lessons, responsibility, etc. , has been attributed to it–like medicine that tastes awful, but does you good, eventually. (Ugh)

It is now the Libran’s turn, Birth Signs and Ascendants, to experience the planet for grownups.  Saturn (transit lasts until 2011) can change this gracious, relationship sign from an indecisive, social coquette to a serious seeker of commitment.  Everything must still be lovely and beautiful, partnerships will be highlighted, but with an underlying base of steel mesh, focus, ambition.

This is about boundaries, “reality”, discipline, karma. Yes, there is a heaviness as it transits a sign, but you can get a lot done with Saturn’s “duty bound” attitude, it just isn’t always fun.

BTW: If you have experienced a recent 30/60 year Saturn Return in Libra (the planet returns to the same place in your chart as at the time of birth every 30 years) you may notice the effects too.
