Lucky Jupiter is currently in the sign of its exhalation, Cancer, meaning that it's well functioning and comfortable. On August 21, the benefic planet squares Uranus, an outer, slow-moving planet associated with personal freedom. Uranus is also now in the feisty Fire sign of Aries, so when these two planets square off on the 21st, the effects are apt to be quite dramatic.
Squares cause friction, spur social movements and create the desire for change. While they may not be comfortable, they're necessary for our evolution. Without a little discomfort, most of us would stay the same and miss out on opportunities for spiritual growth.
The best way to utilize the energy of this Jupiter-Uranus square is to be willing to tell the truth -- both to yourself and those around you. You may need to part with old ways of doing things, especially when it comes to family. This is no time to hide from conflict, but it's not useful to blow things out of proportion either. Face your fears and deal with the issues that are arising, knowing that you're doing your best -- and so is everyone around you.
