A Grand Cross in Astrology is when four different planets form 90 and 180 degree angles to each other in the sky. A 90 degree angle shapes a square aspect, while a 180 degree angle forms an opposing aspect; both aspects denote tension in an attempt to blend energies. There are 3 types of Grand Crosses: Fixed (with planets transiting the fixed signs of Leo, Aquarius, Taurus and Scorpio), Mutable (with planets transiting the mutable signs of Gemini, Sagittarius, Pisces and Virgo), and Cardinal (with planets transiting the cardinal signs of Libra, Aries, Capricorn and Cancer). At this time, Saturn is in the sign of Libra; Uranus is in the sign of Aries; Pluto is in the sign of Capricorn, and your Sun sign is Cancer, completing the cross.
Because your Sun is at one apex of this Cardinal Grand Cross, you have probably felt enormous amounts of pressure in the main areas of life - at home (due to Saturn in Libra), in your career (due to Uranus in Aries) and in your relationships (due to Pluto in Capricorn). Additionally, because Pluto has been transiting your opposite sign and will continue to do so long after Saturn and Uranus leave the signs of Libra and Aries; how you structure those important one-on-one relationships will determine how well you are able to make adjustments in the other areas of life being affected by this Grand Cross. And Cancer, the only way to do this is by tapping into the energy of your Sun.
The Sun in Astrology describes the conscious self and speaks of our approach to life. The constellation of Cancer is the only one without a planet in transit, which means all of the energy flowing from Saturn, Uranus and Pluto is being dumped onto your Sun. It may seem, then, that these planets have the upper hand. But actually, you are in the driver’s seat navigating how this surge of activity will be funneled. Only you can wield this energy with an authentic Cancerian approach, doing what comes natural to you as a Cancer. You are more than capable of uniting the three heavy weights above, and in doing so, you are bound to reach an equilibrium for the sake of your well being. Just keep doing what you're doing!
Happy New Year, Cancer!
