Transit reminder: Mercury in Aquarius makes an easy sextile to Saturn in Sag, at 15 degrees. Take those brilliant but jarring ideas, and organize them. Add some polish to your revolutionary statements. Give your crazy plans a bit of structure. This aspect gives you the best of both worlds, as Saturn sobers Mercury up without crushing Aquarius' spirit.
Sagittarius and Aquarius are both concerned with the big picture, and Mercury/Saturn can make social, religious and philosophical ideals real. And doable.
