Your introduction to Jupiter in Libra is HERE, and more info on how all this applies to you personally (and those around you) is HERE.
Please note that this is covering the transit of Jupiter in Libra to your birth chart, based on your Rising Sign. There is some applicability if you go by Sun Sign, but this will work a lot better for you if you go by the Ascendant/Rising Sign. If you don’t know what yours is, you’ll need a time of birth… and either a site that will calculate your chart or an astrologer.
Jupiter in Libra is in your Fourth House. Cancer and Libra may not be very “compatible,” but the Fourth House is (literally) “home base,” and no Sign benefits from a happy base of operations than Cancer. You’ll be able to find your comfort zone (literally) and catch a break away from the world. A move to a better home is also possible.
Where you’ll be getting your biggest buzz: Somewhere between the couch and the bedroom. Your overall sense of security with life is likely to improve too.
When you’ll need a Designated Driver: Cancer Rising people have a natural fondness for occasionally wandering off by themselves and hiding under a rock… after all, it can be a big scary world, and sometimes withdrawing from it makes perfect sense. Just remember to come out sometimes, okay?
