Here we go with pie-in-the-sky generalizations again.
Jupiter spends about a year in each sign, no? Is it reasonable to expect that there will be parties and cake for everyone throughout the year?
A teaspoon of reality and a pinch of logic never hurt astrology at all. Add those ingredients to some serious study and ....
What does it mean when any slow-moving planet changes signs?
Jupiter: expansion, fortune, luck, foolhardiness, benefactors, teachers, philosophy, law and religion
Cancer: women, children, motherhood, nurturing, moodiness, emotional security, home
Leo: dramatic arts, creativity, glamour, generosity, playfulness, self-centeredness, the individual vs. the collective
So, I'd expect the things Jupiter represents to shift focus from expressions in the domain of Cancer to expression in the domain of Leo.
Interesting to me, the timeline of this court case about "Hobby Lobby" (an arts and crafts company) and birth control.
Jupiter entered Cancer in June, 2013. This is when an appeals court ruled that Hobby Lobby could be granted "religious freedom" as a company. Then in June 2014, the Supreme Court ruled on their birth control case, just before Jupiter left Cancer. Now as Jupiter is in Leo, the decision has been highly sensationalized and publicized in the media, and people are arguing yet again about companies having individual religious freedoms. Does Jupiter have a heavy hand in all this? I think so, anyway.
