Example 1: A man with Venus in Taurus tries to invite on a date a woman with Venus in Libra. The Libra-Venus woman needs everything to be beautiful, refined, cultured, and respectful. The Taurus-Venus man, although he has excellent taste in women (after all, he chose to invite a beautiful lady), makes a serious mistake in how he invites her. Not only does he ask her out “right now,” for a rather late meeting (around 10 p.m.), but he even specifies which slippers he intends to wear – slippers that, in her view, look hopelessly unattractive and utterly unfit for a date.

When she points out that it is inappropriate to set up a meeting so unexpectedly – and at 10:30 p.m., when she’s already getting ready for bed – he replies that “it’s not that late” and that “there’s a first time for everything.” Naturally, the date never happened. Perhaps another woman with Venus in a different sign would have agreed to a sudden late-night meeting – but certainly not Mademoiselle Libra.

Example 2: Another interaction between a Venus-in-Taurus man and a Venus-in-Libra woman: He takes her for a walk in nature (probably one of the few things they have in common). The Taurus-Venus man, like a child, marvels at every mushroom or flower they encounter – and there are many – pausing at each one, admiring it as if he had never seen such things before. He examines them like museum pieces of art and then exclaims with satisfaction, “Cyclamens…” – with deep soulful peace (where I live, these flowers are quite common). By the second time, the Venus-in-Libra lady has to restrain herself from rolling her eyes.

Then they sit on a bench to enjoy the view. Nearby on the ground lies some trash and disposable dishes. Without hesitation and without gloves, the Taurus-Venus man decides that this is his life’s mission and begins to clean it up, which utterly disgusts the Venus-in-Libra woman. Then he expresses extreme views, justifying population reduction and blaming large families for polluting the planet.

The Venus-in-Libra woman shudders at these words – she believes in karma and knows that no soul is born without purpose, and the mere thought of a person deciding who should live and who should not terrifies her. Of course, it’s important to care for the environment, but it’s impossible to control everything everywhere (and who says the litter was left by a large family?).

Naturally, not every Venus-in-Taurus man behaves this way, and certainly there were other factors in his chart that enhanced such mannerisms.

Still, the more planets are 6–8 houses apart in synastry between two people, the more awkward and absurd situations of this kind tend to occur.

The D9 Chart

In Indian astrology, there is the main natal chart (D1) and numerous divisional charts.

One of the most significant among them is the Navamsha (D9) chart, which represents the nature of marriage, the spouse, and self-realization of the chart holder.

When evaluating compatibility, it is essential to analyze both the D1 and D9 charts of both partners.

There is a common belief that if the D9 chart of Partner 1 is “similar” to the D1 chart of Partner 2 (meaning most planetary positions coincide), the couple has a strong potential for a long-term relationship, possibly leading to marriage and family life. However, this appears to apply only when there is mutual resonance (a kind of “cross-link” between the charts). If only one partner’s D9 overlaps with the other’s D1, while the second partner’s chart does not reflect this connection, the latter is likely to sense the imbalance and eventually slip away from the relationship.

Moon Compatibility

One of the most crucial indicators of compatibility is the relationship between the natal Moons of both partners.

If there is no harmony between their Moons – whether by sign or Nakshatra (constellation) – it indicates a connection lacking emotional balance and mutual sensitivity.

I would recommend Ilana Lib’s book “Nakshatras,” which offers excellent explanations of each Nakshatra and a clear matrix of relational dynamics between them. The interpretations in that work are consistently precise and aligned with real-life experiences.

Just like the Moon, the Ascendant sign also plays an important role – it is advisable to check compatibility by both sign and Nakshatra as well.

Sometimes, the Moon of Partner 1 may fall in the same sign or even the same Nakshatra as the Moon of Partner 2 – potentially indicating deep emotional understanding.

However, aspects and conjunctions with other planets can completely alter this picture.

For example, if one partner’s Moon is conjunct Mars in the same house – the Moon + Mars conjunction in anyone’s natal chart is a black flag. We will discuss this in greater detail later.

Common Problematic Configurations in Synastry Between Two Partners

Partner 1’s Moon + Partner 2’s Mars in the same sign or aspect

Drama, ugly quarrels, power struggles, emotional – and in some cases physical – wounds are just part of what to expect from such a connection. At first, there seems to be strong attraction, but the relationship quickly turns strange and unstable.

The Moon person – the more sensitive side – does not know how to cope with the aggressive attacks of the Mars person. Each outburst cuts like a knife from an unexpected direction.

Mars, being a malefic planet, seeks to control and exploit the Moon’s emotional vulnerability, violating dignity and personal boundaries at every opportunity.

There is no mutual understanding; their needs are completely different: the Moon person longs for tenderness and care, which Mars by nature cannot or does not wish to give due to his aggressive disposition.

Partner 1’s Venus 6–8 houses apart from Partner 2’s Mars

These are highly challenging relationships, full of appeasement, manipulation, and emotional dependency. This configuration can lead to abuse, toxicity, or even danger.

One partner may attempt to isolate and control the other’s life or conceal deceitful or harmful intentions (for instance, Venus in Sagittarius for Partner 1 and Mars in Cancer for Partner 2).

A few days after separation, the Venus person often feels immense relief, realizing they have escaped an “irritant” that they previously could not identify clearly due to emotional overload.

Partner 1’s Rahu/Ketu on Partner 2’s Moon (same sign)

This indicates a heavy karmic connection accompanied by emotional turbulence. Sometimes it is seen as a sign of possible marriage, though not always.

If they marry, they will find it hard to part; if not, the separation may be painful and lingering, even when it’s clearly for the best.

Rahu creates an illusory smoke screen of obsessive energy, confusing the Moon and making the Moon person believe they are in love.

Partner 1’s Rahu/Ketu on Partner 2’s Venus (same sign)

Venus–Rahu: Rahu here clouds Venus’s clarity. There may be an illusion of love, distorting one partner’s perception of reality. They are unable to see things as they truly are, even when presented with facts. One partner may be materialistic, seeing the other as a “doll.”

Such relationships rarely lead to anything real (apart from physical attraction) and often end in scandal and betrayal.

If the Rahu person is a man, he is unlikely to remain faithful to the Venus person – he will constantly seek “more women,” especially if insecure or motivated by material gain.

Venus–Ketu: This may indicate a connection from past lives, but it often brings emotional difficulties.

Conflicts arise due to opposing desires – one seeks romance and pleasure, the other distance and detachment.

The outcome is uncertain; most often it suggests a short-lived relationship. Additional factors in both charts must be analyzed for a full picture.

Partner 1’s Rahu/Ketu on Partner 2’s 1–7 House Axis

A karmic bond often found in married couples.

There is an unconscious attraction to partners who may seem unusual or eccentric.

Balance between individuality and partnership is crucial to avoid issues with self-identity and relationship definition. If both partners decide they are together, they must remain faithful and committed, not justify unfaithfulness with the idea of an “open relationship.”

Such a bond is worth pursuing only if there is true love and proven trust. Disillusionment may follow initial idealization, leading to instability, misunderstandings, and misplaced criticism. The only way to improve such a connection is through mutual spiritual awareness and conscious work on the relationship, along with individual spiritual practice.

Partner 1’s Pluto + Partner 2’s Moon (same sign or aspect)

A particularly heavy – sometimes deeply karmic – connection that may leave one partner psychologically traumatized. The attachment is intense yet destructive, and separation is painfully difficult despite the problems.

There is emotional blindness to manipulation, domination, and vulnerability.

Explosive arguments arise out of nowhere.

Partner 1’s Pluto + Partner 2’s Venus (same sign or aspect)

This pair is filled with passion and intensity, but such relationships can end in heartbreak, exposure, and collapse.

Separation may feel like a black hole in the heart. Such couples often reunite again and again after breakups – they struggle to cut the energetic ties.

However, one must learn to let go if the relationship is destructive.

One partner may be clearly dominant. It is advisable to remain in such a union only if both maintain balance, maturity, and seriousness in the relationship.

Partner 1’s Pluto + Partner 2’s Mars (same sign or aspect)

This combination often breeds ego games, aggression, and even violence – verbal or physical. A dangerous configuration where at least one partner dominates excessively.

If either has behavioral issues or tendencies toward aggression, the situation is highly serious, and such relationships are strongly discouraged from the start.

Partner 1’s Saturn + Partner 2’s Mars (same sign or aspect)

Mars wants to act in a certain way, but Saturn restricts him.

The problem arises when Saturn’s restraint comes from differences in values, which Mars refuses to accept or understand. For the Saturn person, it’s a waste of time to enter a relationship lacking axiological (value-based) and spiritual compatibility.

Partner 1’s Moon/Venus + Partner 2’s Mercury (same sign)

This can bring lively communication and even pleasure in the relationship (especially Venus–Mercury), but it rarely indicates long-term union.

Such romances often end within a few months – typically under half a year.

The Time When You Met

Regardless of both individuals’ natal charts, planets in the sky never stop moving – they continue to transit from house to house and trigger situations. The transit chart shows directly whether the time is favorable for romantic encounters.

When the timing is unfavorable, even if you meet someone, they won’t be right for you.

A person may appear who, if you overlook their major flaws early on, will cost you precious time and emotional energy. It’s crucial to be aware of what’s happening in the sky while keeping your feet firmly on the ground.

Sometimes people believe that when Jupiter transits the 7th house, the woman may meet her future husband or get married – but that’s not always the case. Possible reasons include: other planets are not positioned in houses conducive to marriage; the current planetary period (Dasha) does not support relationship formation; or Jupiter’s Ashtakavarga strength relative to that transit is weak.

For example, if Jupiter transits through Taurus, which is the woman’s 7th house, but in her Jupiter Ashtakavarga chart Taurus scores below 4, the chances of meeting her future husband during that transit are extremely low – even if other planets seem favorable.

The number indicated in each sign in the Ashtakavarga chart represents how many “liters of fuel” the planet has in that sign/house: 1 or close to 1 – “the tank is almost empty,” 4 – neutral, 8 – “the tank is full” – the planet has enough energy to manifest the transit’s promise.

Sometimes, a planet may transit a sign with a low score in the Ashtakavarga, yet the event still manifests – this happens due to planetary aspects from other signs that hold higher scores and reinforce the outcome.
