This method follows traditional approaches of Hindu Astrology and reflects aspects of Hindu culture. While the language may be difficult for us to understand, it can yield much useful information and is much simpler to do as we can simply look up the compatibility between different Nakshatras.
The traditional Indian method of judging compatibility included weighing different factors and giving them certain unit strengths. If the charts have a certain number of such points, they are regarded as good for relationship. If they fail to gain the required number, they are considered to be questionable for happy marriages. Most of these factors are based on the lunar constellations or Nakshatras, which we examine in more detail in Part III of the course. For the locations of the Nakshatras in the zodiac, please examine that section of the course.
While some factors in this method of computation appear strange at first, others follow obvious astrological principles. While we need not take each one of them too seriously in itself, the overall value they show can be an important index of compatibility. Yet such mechanical computation methods should not substitute for a more detailed chart analysis. They are a numerical short cut that is generally helpful but may not be enough in itself.
Below we examine how these factors are calculated. At the end of this section we present a computation sheet that shows the final number so that we don't have to go through all these procedures ourselves. Nevertheless, it helps to understand their foundation.
The idea is that the woman being feminine in nature should have a Nakshatra in a feminine (even numbered) relationship from that of the man.
The Nakshatras are classified into three temperaments or energy types (gana) as Deva (divine), Manusha (human) or Rakshasa (demonic). They generally correspond to sattvic, rajasic and tamasic qualities. They also have an energetic effect.
These groups do not of themselves make the individuals born under them of higher or lower spiritual nature. That comes from the chart as a whole.
Generally, one should marry a person of the same Gana. It is also considered that a Rakshasa man can marry a Deva or Manusha girl, but that a Deva or Manusha man should not marry a Rakshasa girl. These Ganas are as follows:
This factor counts for six units. Some astrologers say that if the Nakshatra of the woman is more than 14th from the man, this problem can be ignored.
We also note that Deva Nakshatras are good Moons under which to proceed with any favorable actions. Manusha are moderate, and Rakshasa are usually not recommended. We can note their effects under the section of Part III on Astrological Forecasting Part 1, to see their nature and results.
It is good if the Nakshatra of the man is 4th, 7th, 10th, 13th, 16th, 19th, 22nd or 25th from that of the woman.
The Nakshatra of the male should be at least nine away from that of the female. By some accounts seven is enough. The idea is that some distance between the Moons is helpful for compatibility. This consideration can be ignored if Rashi Kuti (factor 6) or Graha Maitri (factor 7) prevail.
