Sample Relationship Report for Prince Charles and Princess Diana

The traditional method of relationship compatibility based upon the Moons of the couple determines their fundamental compatibility. It measures the flow of the life force, or energy, between the two people, whether harmonious or inharmonious. This energy must flow from a positive to a negative terminal, just like a battery, for best results. Any obstructions to this flow may create a loss of power and therefore inertia, or a short circuit that may quickly heat up and explode. Several of the matchings measure to see if there is such an obstruction to the flow of the couple's energies. Vedha, Rajju, and Strii-Diirgha are these most important matchings and any one of these that is afflicted will cause serious difficulties within the relationship. If Rajju, Nadi, or Rasi are unacceptable, there may be an exception present that wards off the great difficulties that may be created; the relationship will its weaknesses, but ones that are workable. If Strii-Diirgha is afflicted, but the exception for Rasi Kuta is met, then Strii-Diirgha will be OK as well.

In addition to the flow of energy, there must be high enough voltage. The total points of eight of the Kutas determine this. The higher the score the more similar the "taste buds." This gives a greater capacity for a compromise that allows both individuals to feel fundamentally good about what they're getting. Seventeen points is the average, twenty or greater is ideal.

If the matching of the Moons is adequate the couple will have the capacity to relate in a manner that allows the love to flow and for both of them to grow in a positive way. Karmic and behavioral factors will modify to which extent they will fulfill this capacity. If the matching of the Moons is inadequate the couple will find it difficult to flow together; their very life force will not harmonize well together. In this case there is little that they can do, but to accept the fact that their energies collide or miss each other at times. They can consciously attempt to create a better flow, but at times they will fall back onto their natural, disruptive flow, especially during times of stress or fatigue.

Why the Moons? Because....

1. The Moon is the "Manas, Mind, in which lives the Jiva: the self, with Ahamkara, the Ego, the idea of separate existence." -Sri Yukteswar. The Moon, therefore, indicates the compatibility of the two selves.

2. The Moon is the social planet that lets people's energies flow together. Whether the relationship flows in such a manner as to create mutual respect and increase in love, or whether it flows in a manner that causes disrespect and loss of love is largely dependent upon the Moon.

3. The Moon is the conditioned consciousness; what is most comfortable, familiar and innate to the individual. It is most important for those living together and spending a great deal of time with each other to be comfortable with each other and to offer support to one another. 

Vedha- Obstruction

Fortunately you don't have the blemish of Vedha, which, had it been present, would have brought many insurmountable obstacles to your desires for each other. This means that you two will be better able to make the relationship what you want it to be, without attracting obstacles to your goals for each other. 

Rajju- Rope

Rajju, the second most terrible blemish, is not found in your compatibility. This is great news and indicates that you both have the potential for a great relationship with a healthy degree of mutual dependence, if you both are relatively mature and free from unhealthy codependent behavior. If one or both of you are still learning how to have a healthy relationship then, since your compatibility is free from the blemish of Rajju, you can learn together to have a relationship with a healthy degree of mutual dependence. 


You don't have Strii-Diirgha matching. This means that the distance from the woman's Moon to the man's is not far enough; the shortest distance is from the woman's Moon to the man's. This causes the creative energy in the relationship to flow from the receptively centered female to the action and initiative centered male. Masculine energy and, therefore, most men feel most loved when their thoughts and actions are respected. Feminine energy and, therefore, most women feel most loved when their feelings are respected and they are loved for themselves, rather than for what they do. Since Strii-Diirgha is not present the energy tends to flow from the woman to the man, causing her to initiate more of what happens in the relationship. This causes the woman to wonder and question if the man is really there for her; if he thinks of her and loves her, since she is doing more, investing more, etc. in the relationship. She generally finds it more difficult, therefore, to feel secure in the relationship. The man, in fact, usually does think of her, but before he is ready to begin or initiate something, it is already getting too late for her and by then she feels like she has to get things moving. She also does not have the opportunity to be cherished and loved for herself, since she is more often thrown into the active, doing role in the relationship. The man also suffers as a result of Strii-Diirgha not being present. Since the creative energy tends to flow from the woman to the man, he has little opportunity to have his actions and thoughts respected, resulting in him not feeling loved. Before he has finished a thought or initiated an action, the woman most likely has already done so or, if not, she has already asked him to do it. If she has already done so, then there is no room for him to be appreciated for what he may do for the woman. And worse, if she always asks him to do stuff, then he begins to feel pressured or nagged.

Feminine energy bonds when it receives, masculine energy bonds when it gives. (When a woman receives a gift from a man, she feels, "He loves me." When a man receives a gift from a woman, he thinks, "Great, I don't have to spend my time shopping for underwear, etc." and then he may think, "How nice/sweet of her." Only occasionally will he think, "Wow! She loves me.") Therefore, when Strii-Diirgha is not present and the energy flows from the woman to the man and the woman is put into the more active, doing, giving role and the man into the more receptive role, neither person bonds fully to the other. However, feminine energy bonds stronger sexually than does masculine energy, so after having sex the woman ends up being more bonded to the man than he is to her. Strii-Diirgha not being present has not allowed the man the opportunity to invest in giving the necessary time, energy, money, thoughts, etc. into the relationship that would bond him to the woman. The result is that eventually the woman is more bonded to the man than he is to her and so even though she may do everything for him, he will eventually leave her. That is why this matching is called Strii-Diirgha- length of wife, if it is not present the relationship does not last long and the woman suffers most because she ends up being the more bonded of the pair. If, on the other hand, the relationship does last longer, then the woman usually ends up drained from all her doing, until finally she has to leave. The lack of her being cherished and not receiving has not recharged her.

Since the communication between the two hemispheres of the brain in a woman's brain is much faster than that in a man's, a woman has a lower capacity to do something she has planned when she no longer feels like it than does the man, since her emotions can so suddenly override the rational, determined side of her brain. Therefore, in times of duress in the relationship, since Strii-Diirgha is not present, the woman, who may be emotionally sick of the relationship at the moment, is forced into the role of deciding what to do with the relationship. At that moment, her emotions having a high capacity to overrun the rational side of her brain can cause her to forget about the good the relationship has given and any commitment made, she can only feel that the relationship is perhaps not meant to be. So she goes to the man and says, "I don't think we should be together." The man replies, "maybe you are right," because the lack of Strii-Diirgha has not allowed him to organize his thoughts and decide how to handle this problem, and he doesn't want to risk infuriating or hurting the woman more by arguing at that moment. This reply usually makes the woman feel worse, because what she really needs to hear is, "We have a pretty good relationship and love each other, we can work this little problem out, etc." Not hearing this, she does not feel secure in the relationship, and even if they do get back together in a few days or few weeks time, the foundation of security has been weakened.

Since the communication between the two hemispheres of the brain in a man's brain is much slower than that in a woman's, a man has a lower capacity to do take in something new when he is already engaged with something else and see how he honestly feels about it. Therefore, since Strii-Diirgha is not present and the energy in the relationship flows from the woman to the man, the woman may often come to the man and propose something to him while he is otherwise engaged. It can actually take him 20 minutes just to see how he feels about her proposal, during which time he is generally feeling irritated, pressured or nagged and she is felling unimportant, not heard, or not cared about.

As can be seen, Strii-Diirgha not being present can create a host of problems. It is, in fact, one of the main reasons that relationship fail after time. Fortunately the worst effects of Strii-Diirgha are avoided and the relationship becomes possible if Rasi Kuta is met, or if there is an exception to Rasi Kuta not being met, so keep reading and find out if you will be able to make this work. 


You don't have Rasi matching. This gives the same troublesome effects as not having Strii-Diirgha, as already mentioned. 

Classical texts state, "If the mans rasi is 4th from the woman's there will be poverty and enmity." This position makes it very difficult for the couple to offer emotional support to each other. 

Fortunately the lords of your Moon's are the same or friendly to each other and the most troublesome effects of Rasi and Strii-Diirgha not being present are reduced. This means that you have more similarities that will help keep you from disrespecting each other. So, with a reasonable amount of work, growth and maturity, you can make this relationship work. It will never be as good as if Rasi was present, but if there are real reasons to be with each other it will be well worth the extra work or compromise required. 


Both of your Moons' Nadis are windy, this can create huge imbalances in each other and in your relationship, so you do not gain 8 points towards your total compatibility score. Since both your Moons are in a windy Nadi, you will find it more difficult to be grounded and focused when in each other's presence. This not only creates difficulties in small things, like not having a clear idea of how to proceed or what to do at times, but also with the big thing of what to do with the relationship. There tends to be a lack of concrete goals for the relationship, which results in the woman eventually feeling very insecure with the relationship, therefore, the classical texts state, "The woman will die when both the Moons are in windy Nadis." 

Fortunately, even though your Moons are of the same Nadi, the lords of your Moons are either the same or friendly to each other, which reduces the negative effects of the excess fire, water or wind so that it is not disastrous, only inconvenient at times. As a result of this, even in times of the stress that having the same Nadi's can bring, you will feel connected to each other, which makes you feel like you belong together even during those times of difficulty. During these times there will also be a greater element of friendliness present that will reduce any disrespect you may cause each other during any times that the excess fire, water, or wind causes a disturbance.  

Bha "Sign" Kuta

Moons conjunct, in 7th from each other or in 3/11 or 4/10

Your Moon's are in favorable positions from one another. This helps you all share in your mutual goals. Additionally, this also helps you all to be constructive together and build a productive life together.  


The woman's Moon is in a Rakshasa (demonic) nakshatra and the man's Moon is in a Deva (angelic) nakshatra, which is not good at all so you do not gain any points towards your compatibility score. Women with their Moons in Rakshasa nakshatras are temperamental and their emotions can make them go to extremes at times, and a man with his Moon in a Deva nakshatra will not be able to appreciate her. Men with their Moon in a Deva nakshatra will be a bit too sensitive to handle a woman like this and can find themselves feeling hurt quite often, even when it is not the intention of the woman to do so. The man will also not have the ability to settle her at times when she is feeling an extremely turbulent or depressing emotion, or when she goes off on some extreme tangent. Only another man with his Moon also in a Rakshasa nakshatra can do that effectively. Though this can be very stressful at times and cause you to wonder why you are with each other because you are so different in some respects, if Vedha, Rajju, Strii-Diirgha and your Total Points are okay, you can still have a decent relationship together. 

Fortunately, even though the woman has her Moon in a Rakshasa nakshatra and the man doesn't, the lords of your Moons are the same or friendly towards each other. You, therefore, have the extra bit of affinity that will help you understand each other and you will be able to maintain a feeling of friendship that will prevent you from disrespecting each other. As long as Vedha, Rajju and your Total Points are okay, you will, therefore, be able to have a decent relationship. 

Graha Maitram

The lords of your Moons' rasis are the same or friendly, which gains 5 points towards your total compatibility score and greatly supports your affinity and like-mindedness. You will have many similar tastes and be very comfortable with the same types of things. There will be greater feelings of friendship and mutual understanding, and compromise, when necessary, will be quite easy. You will also react to situations very similarly, which can allow you to operate like partners in more situations. 


The Yonies of your Moon's are the same, which is excellent and earns 4 points towards your total compatibility score. Your deeper, primal, instinctual natures are identical. You will be better able to share any intense experiences, including sex, and be better able to deal with intense situations together. 

The sexes of your Yonies are different, which helps your deeper, primal and instinctual natures to connect. You will better be able to enjoy and bond through intense experiences.  


You do not have Tara matching, so you do not earn 3 points towards your total compatibility score. The Man's Moon falls in an unfavorable nakshatra from the woman's, thereby reducing the possibility that she feels good about what he proposes to her. It can therefore be a bit more difficult for the woman to be cherished and the man to be appreciated for what he does. This will only be a problem if one or both or you tend to be demanding, in which case one or both of you will end up feeling disrespected and not very loved. If, on the other hand, you are both easy going and not pushy or demanding, then Tara not being met will cause no real problems as long as your Total Points are okay. 

Vasya "Dutiful" Kuta

One Moon Vasya to the other.

The person who's Moon is Vasya to the other will be more attuned to what it is that the other needs, and will more happily provide that need because they understand it. The other will appreciate this and, as a result, feel more devoted to the other. This gains you 1 point towards your total compatibility score. 


The man's Moon is in a Vaishya rasi and the woman's in a Sudra rasi, earning 1 point towards your compatibility score. The man's desire to explore life and pursue interests will stimulate and excite the woman's to pursue more interests as well. 

Total Points

Following Vedha, Rajju and Strii-Diirgha, the next most important factor to consider in your compatibility is the total points gained through the 8 matchings: Nadi, Rasi, Gana, Graha Maitram, Yoni, Tara, Vasya and Varna. The Moon represents nourishment and what you need to feel nourished, not just in the sense of food, but anything that you take in, through any of your senses, which all serve to stimulate your life force one way or another, and which have a subtle influence on your mental and physical well-being . The total points between your Moons indicate the similarity of your needs and your ability to both be fulfilled and happy with continued exposure to each other. The higher the points the more you will feel like the same thing at the same time. You will be on a more similar 'wavelength' and have more similar 'taste-buds.' This makes it easy and natural for both of you to be fulfilled. If the points are low, you will have different needs and require different things in order to feel comfortable and 'right.' 

The total points between your Moons is 18.0. 

Your points are average. This means that on occasion you both may have some different needs to fulfill and that a bit more compromise will be necessary at times. Your points are not so low as to raise alarm, and if Vedha, Rajju and Strii-Diirgha are acceptable, you can have quite a decent relationship. There will be a bit less mental rapport than ideal, but not so much less as to actually cause problems. Just be aware that you may have to make a little more effort to communicate clearly with each other because you won't always be on the same 'wavelength.' Occasionally you may also have different cravings or needs, but if you are willing to make allowances for these times and both fulfill your needs independently you will be able to have quite a good long term relationship. 


You don't have Mahendra, which is a special inner connection that helps a couple find long-term soul purpose in their relationship and which can help make your relationship more and more meaningful. This is not a common connection and is not necessary; many very successful marriages do not have Mahendra. Just be sure you are getting involved for good reasons and that you have mutual long term interests, hopes and desires to share so that you continue to find meaning and purpose in your relationship. If your relationship is founded upon frivolous things you will quite likely find out in the future that there is really not that much purpose in being together. 

Vasya "Subjected To Another"

Vasya is not present between your Moons. Vasya is an uncommon connection that creates a bit stronger of a bond between the couple. When present it adds a bit of attraction that insures that the couple wants to stay together. When not present it really does not make much difference by itself.

This is a different Vasya than the previously mentioned Vasya. This Vasya results in a magnetic attraction instead of the attunement to each other's needs as the does the other Vasya. 

Prasna Marga states, "If the couple loves each other, they can enter into wedlock, even if there is no agreement in other ways. This is very important in the matter of marriage. One who loves a girl sincerely, from his heart should marry her. Pure love is greater than any other virtue."

This is to say that you should marry whom you want, but that does not mean that your compatibility should be ignored. It does not mean that love will remove the blemishes of poor compatibility. It only means that if you think it is worth having the relationship, even in the face of greater than average difficulties, you should. Poor compatibility indicates that the price of the relationship will be higher. It will take more time, energy, work, patience, and there will be more distress and ups and downs if your compatibility is poor. If you find it worth paying that price, then you should go ahead with the relationship. Look at the compatibility in order to really see what the relationship is, to really see if you want the relationship, and to see if you can realistically do what is necessary. The average person finds a relationship that fails Vedha, Rajju, Strii-Diirgha or Points eventually becomes more than they can realistically handle, so if any of these are missing, take a very good look at your relationship.

This is also to say that even if the compatibility is good, if one or both of you cannot love and relate healthily then you will not be able to take advantage of a good compatibility. If the compatibility is good and you are still having problems you will have to take a good hard look at yourselves. The good news is, that if the compatibility is good, any work you do on yourself will support and benefit the relationship. The relationship will also be a better arena for you to learn what you need in as healthy a manner as possible. If on the other hand, the compatibility is not good, then even if you work on yourself the relationship will not benefit much, or even at all, and you will find yourself in situations with your partner that really bring out the worst.

The important point about this method of compatibility is that, it indicates whether the relationship will flow in such a manner as to create mutual respect. Out of respect grows love, out of disrespect grow hurt feelings and frustration. When it comes to arranged marriages, this compatibility is, therefore, obviously important. When it comes to modern society that marries out of love, it is equally important, because after years of mutual disrespect many, many couples that once loved each other divorce. Mutual respect is the key to all human relationships, because from that grows real love.
