And you're certainly feeling it now.
This is not the first time you've experienced tension between Jupiter's expansion and Saturn's limits. It happened on March 23rd, 2016 (at 16 degrees) when Jupiter was Rx and Saturn was direct. March 23rd featured a Full Moon eclipse in Libra , so there may be a return to some issues from that time.
As Jupiter moves ahead with improvements, Saturn will ensure that everything Jupiter offers is up to snuff. The blizzard of intel that Jupiter in Virgo can bring will be fact-checked. Only the useful details will be considered. Saturn Rx's review of the rules will put Jupiter's ideas into context. Reprioritization and reorganization will be key, and the "re" will be on Saturn's end. With Jupiter Rx square Saturn, you were reviewing the information itself. With Saturn Rx square Jupiter, you're reviewing the context the information is in.
The net result is the same, either way: unnecessary details will be cut out. Will this undermine the Grand Earth Trine that Jupiter is part of? Not at all. It will help you make sense of any developments, while drawing your attention to opportunities you may be ignoring. Saturn's limits always focus you on the essentials. Saturn square Jupiter will push you to make the most of what you know, or what you want to implement.
I've described Jupiter in Virgo as the elevation of detail, and that elevation becomes even more effective with Saturn. When details are focused, you can create something extraordinary (life-altering truths and profound improvements). Rather than fighting against Saturn's restrictions, use the limits to cut out distractions.
On May 27th, Mars Rx will back into Scorpio. I'll write about that in a separate post, but for now, consider the timing. Saturn nails Jupiter's ideas to the wall for examination, and one day later, Mars dives deep into Scorpio for some transformative insights.
If you have anything from 12 to 14 degrees of the Mutable signs, you'll feel this square most strongly.
