Numerology Life path 7 & Karmic number 7 is ruled by planet Neptune & south node Ketu. 7 is the most spiritual & Masonic number in numerology, and to be spiritual and find enlightenment one has to be with thyself. This is why 7 people in numerology are loners, and lone souls but they choose to be this way. 7 loves to be by themselves for most of the part and observe life around them. They like to take notes and remember them for their writing later; seven make the best writers/novelists. In order to write about anything you have to know that subject in-&-out, and this why 7's observe life everyday and try to know all the aspects of their lives and people around them. 7's are either very artist, or very studious but never both. You may find 7 life path & 7 karmic number people as teachers, professors, and mathematics, or you will find them as writers, actors, directors and painters.
Best profession for a 7 is to work for themselves, as they hate authority, schedule and limits. They can become best writers, novelists, film directors & editors, or they can become researchers in a lab. 7's are compatible with 1,2,4 and 5. Two 7s together do not make a good combo, as both will try to ignore the other to be by themselves. 7 is similar to number 2, as moon is also a co-ruler of 7, however the reason why Ketu is assigned to this number is because Ketu is about isolation & spirituality.
However, Numerology has its limits, and it can not predict in detail the timing of events, such as marriage, birth of a child, career, promotion, death, accidents, birth. This is when Vedic Astrology far exceeds the speed limit of numerology, but numerology is still important and the easiest way to find out your 'destiny'.
