The branch of astrology that studies relationships by comparisons of natal horoscopes is astrological compatibility (synastry). A natal horoscope is a diagram or map of planet angles in the Solar System at the precise time of birth of a person and its location within the zodiac. The positive and negative relationships between the planets reflect these angles. The relations between the two individuals under consideration are defined in these relations.
Within a specific branch of astrological tradition: western astrology, vedic astrology or Chinese astrology, compatibility between Zodiac signs is often approached. Carl Jung in his book Synchronicity most clearly demonstrated this principle in the modern times. Jung was exploring the nature of coincidence for a study. He was offered a collection of over 400 pairs of horoscopes of married couples for this purpose. Jung randomized half of the pairs of horoscopes and attempted to find the couples who were actually married. Jung found a correlation between the married couples that matched astrological prediction.
Astonished, he questioned his influence in the study and repeated the experiment with the same results. He again changed his methods and again arrived at the results astrologers predicted. He could not find a causal relationship to explain his correlations, so he termed Synchronicity an acausal principle. In modern times, Carl Jung’s work in his book Synchronicity most clearly illustrated this idea. Jung was researching the existence of a research coincidence. For this reason, a selection of more than 400 pairs of married pairs was offered.
Jung randomised half of the pairs of horoscopes and sought to identify married couples. Jung found a link in astrological prediction between the married couples. He was shocked that his power was challenged and the experiment with the same findings replicated. His methods were modified again and the astrologers forecast the results again.
A host of other variables, such as longevity of individuals and of people, character (sex), widowhood, poverty, progeny, body state, radical forces and sign, planets and affliction, major and minor time currency, the Marakaas (death-inflating planets), Marsh’s place of birth (Mangal Dosha). The following aspects for evaluating compatibility have been investigated in the light of birth conditions: Varna, Vashya, Tara, Yoni, Gana, Graha Maitri, Bhakoota, Nadi, Mahendra, Vedha, Rajju, Stree Deergha, Linga, Gotra, Varga and Yujja.
Other systems have only 8 numerical values: Varna(1 point), Vashya(2 point), Tara (3 point), Yoni (4 points), Graha Maitri (5 point), Gana (6 point), Bhakoota (7 point) and Nadi. None of those factors are more important than others (8 points). The sum of these variables is 36 points and only if the compatibility score is higher than 18 is considered to be a horoscope.
Different compatibility considerations are as follows:
Varna: degree of spiritual development, obedience
Vashya: Testing one another—friendship.
Tara: Shared charity-luck-spirits.
Yoni: sex, affinity, urgency and compatibility.
Graha Maitri: Friendship in a psychological way.
Bhakoota: kids, family development.
Nadi: Temperament, inherited (astrological), anxiety and death.
Mahendra: Promotes attachment, longevity increase.
Stree – Deergha: husband’s service.
Rajju: Mariju’s happiness and length.
Mutual repellence and hostility. Vedha–Varga.
Varga: Mutual affection and animosity judged by names
Yuja: Mutual love sort – both sides, on the one hand.
In order to match, mathematical calculation is conducted on the basis of the above aspects. The reasoning is this – one of them has no knowledge about their compatibility when two people from different backgrounds come together. This is used to work out using a mathematical algorithm of planets and their positions. The astrologer has to use his skills to verify compatibility in some cases based on the correspondence required.
Before further marriage negotiations are concluded, it is deemed important to match horoscopes. But in ancient books it is specifically stated that such matches should only be investigated in the event of an arranged marriage. In a love marriage there is already a match of mind and all this match is overriding by love. The correspondence of the minds has no significance for the horoscope. Even if all the above matches are present or lacking, love marriage will proceed well. For the last two thousand years, this method has been in operation.
