AQUARIUS (January 20 - February 18) Have you been having problems with someone, either in person or online? If things have been rather tense, now's the time to swallow your pride and start communicating and compromising.
CAPRICORN (December 22 - January 19) Are matters involving home, family, domestic arrangements, parents or property dominating your thinking? Things will gradually improve, as long as you stay centred and keep an open mind.
CANCER (June 21 - July 22) Work projects are favoured, as you make the most of the Sun, Mercury, Venus and Uranus visiting your career zone. Creativity and motivation are high but try to keep a sense of perspective.
LEO (July 23 - August 22) Party-loving Lions are keen to socialise and circulate; mix and mingle; imagine and create; as you let your hair down and have some fun. But it's Equinox day so try not to overdo things!
PISCES (February 19 - March 20) You're thinking about a financial, business or work project as today's planetary patterns help you tackle tasks with extra energy and enthusiasm. But things won't happen overnight!
GEMINI (May 21 - June 20) Open and honest communication is the secret to success at the moment. There'll be plenty of opportunities to expand your peer group. But don't neglect your long-term friends in the process.
TAURUS (April 20 - May 20) The planetary patterns give tired Taureans a welcome energy surge today. The stars also favour some quiet contemplation, as you use your intuition to help you solve a current problem.
SAGITTARIUS (November 22 - December 21) You're in the mood to help a loved one through a rough patch, or cheer up a close friend who is down-in-the-dumps. If you get drawn into a fiery discussion, strive to be balanced and fair-minded.
SCORPIO (October 23 - November 21) Scorpio is the sign of extremes, and you can have trouble relaxing. As we celebrate the Equinox - when day and night are of equal length - strive to bring more balance into your busy life.
LIBRA (September 23 - October 22) It's time to get talking with your nearest and dearest about subjects you may not necessarily feel comfortable about. Try to be fair and balanced, as you view things from differing perspectives.
VIRGO (August 23 - September 22) Business ventures are brewing at the moment, as you combine common sense with intuition to achieve a positive result. Don't be impatient though. Your dreams will take a while to manifest.
ARIES (March 21 - April 19) Are you being too subjective about a current issue? Take a step back, adjust your focus, and strive to view the situation from a much broader and wiser perspective. Balance is the key.
I'm not quite sure where you got this from but the simple answer is no. The closest thing to doubles I can think of is an identical twin although the only real method of communication between them is talking many also have an empathic connection simply because of how close they are to one another.
As for an individual having nine lives and no double again the simple answer is no. There is a saying that cats have nine lives but that's the only connection I know of.
The 'double' I think you are referencing is in Germanic lore, called the Doppleganger. It is said that this is either a physical person that is exactly as you are, though a separate body and mind, and that if you would meet, both would die. In modern Occult lore, a Doppleganger is considered a double of your spirit (and, you obviously don't die if you meet). Some people beleive they are real, some don't. It's all highly diverse when it comes to personal spirituality.
If you do beleive in them, communication with them would be the same as talking with any other spirit. You just have to remember that spirits don't always 'talk' in fully verbal sentences, but you can hear them, see them, feel them, smell them (even taste, as smell is it's mother sense), simply know what they are trying to say. All of this, however, comes with a gut feeling. Instinct is your best friend when it comes to anything spiritual, along with reason.
