One of the requirements of any Saturn-Pluto interaction is that we learn how to navigate situations that are outside of our control. We've had experiences recently of that effect -- just when we thought we had something figured out, a new direction to move in, or the solution to a problem found, we look around to see what appears to be a reversal.
It's good to keep in mind that we couldn't be aware of the "one step back" if we hadn't already made the "two steps forward." And, it's important to realize that these two planets are very thorough, and are not likely to move past a point if there are any details left to be taken care of (Saturn) or structural problems to be revealed (Pluto).
We've been working with the current Saturn-Pluto square since early this year, and are now slowly moving toward the final exact aspect on August 21. Next week's grand cross formation, which involves Pluto and Saturn and five other planets, should reveal even more about where we still need to take responsibility for creating change, rather than trying to find a convenient party to blame.
