Should I Marry This Person? A 5-layer Vedic check.

Anyone asking whether they should marry someone is asking a decision question. Vedic astrology cannot make the decision for you. What it can do is read the structural compatibility of two charts and tell you what the chart-layer says about the marriage's structural conditions. The reading is descriptive, not prescriptive. This piece walks the five layers a classical compatibility check covers. Layer 1 is the Ashtakuta gun-milan (Sanskrit: eight-pillar compatibility scoring) from the two Moon nakshatras. Layer 2 is the Manglik (Mars affliction in marriage houses) check with the cancellation conditions. Layer 3 is the 7th-lord (saptamesha, ruler of the 7th house) cross-matching between the two charts. Layer 4 is the D9 Navamsa overlay (the 9-fold divisional chart used for marriage durability). Layer 5 is the mahadasha alignment (planetary period) for the marriage window. Each layer scores green, yellow or red. The composite tells you what the chart-layer says. The decision remains yours. Computation: Swiss Ephemeris with True Pushya Paksha ayanamsa.

A 5-layer Vedic compatibility check covers the major classical dimensions for a "should I marry this person" reading. Layer 1: Ashtakuta gun-milan scored out of 36 from the two Moon nakshatras. Layer 2: Manglik check both sides with cancellation conditions. Layer 3: 7th-lord cross-matching across the two charts. Layer 4: D9 Navamsa overlay running the previous layers at the durability layer. Layer 5: Mahadasha alignment for the marriage window. Each layer scores green, yellow or red. The composite is the structural reading. The decision is not. Computation: Swiss Ephemeris with True Pushya Paksha ayanamsa.

How to read this check

The 5-layer check is structured so that each layer can be scored against a specific dimension of compatibility. Read the layer description, identify what to check on your chart and the prospective partner's chart and score the layer green, yellow or red. Then read the composite at the end. The layers are weighted equally in the composite reading; classical practice does not rank one layer as more important than another, because each layer reads a different dimension of the marriage question and the dimensions do not substitute for each other.

Two notes before the layers. First, the check is most useful when both birth details (date, time, location) are available with reasonable accuracy. The Ashtakuta layer needs the Moon nakshatra, which requires accurate birth date and time. The Manglik check, the 7th-lord cross-matching and the D9 overlay all need the rashi chart, which requires the rising sign (ascendant), which requires accurate birth time. Mahadasha calculation needs the Moon nakshatra start point, which requires accurate birth time. If either partner's birth time is unknown or significantly uncertain, the check operates with reduced precision; the Ashtakuta layer alone (Moon nakshatra-based) can still run with the date and approximate time but the other four layers need the rising sign.

Second, the check operates at the chart-level. It does not read individual behaviour, individual choices or the specific life circumstances the partnership sits inside. A chart-level compatibility reading describes the structural conditions on which the marriage will be attempted. The actual marriage outcome remains a function of what is brought to those conditions actively from outside the chart-layer.

Layer 1: Ashtakuta gun-milan

The first layer is Ashtakuta gun-milan. The Sanskrit name translates as eight-pillar compatibility scoring. It is the classical Vedic framework for matching two charts at the Moon nakshatra layer, producing a score out of 36 from eight separate factors. The factors are weighted differently. Varna gives a maximum of 1 point and tests varna compatibility. Vashya gives 2 points and tests dominance compatibility (which partner influences the other). Tara gives 3 points and tests birth-star compatibility (Tara counting from one Moon nakshatra to the other). Yoni gives 4 points and tests instinctual compatibility through the Yoni animal symbol of each nakshatra. Graha Maitri gives 5 points and tests the friendship of the two Moon lords. Gana gives 6 points and tests temperament compatibility through three categories (Deva, Manushya, Rakshasa). Bhakoot gives 7 points and tests Moon-sign relation between the two charts. Nadi gives 8 points and tests genetic-and-temperamental compatibility through three Nadi categories (Adi, Madhya, Antya).

The scoring convention. The minimum acceptable score for marriage in conventional practice is 18 out of 36. Scores below 18 are typically read as structural Ashtakuta incompatibility. Scores between 18 and 24 are read as acceptable but not strong. Scores between 24 and 32 are read as good compatibility. Scores above 32 are read as strong compatibility, though scores in the very high range are sometimes treated with caution because they can mask other layer problems through the high Ashtakuta number alone.

Nadi dosha is the heaviest single negation in the Ashtakuta system. It occurs when both partners fall into the same Nadi category (both Adi, both Madhya or both Antya). The classical reading is that same-Nadi pairings carry genetic-temperamental similarity that registers as marriage friction at the deepest layer. Nadi dosha conventionally requires specific remediation before marriage proceeds. Bhakoot dosha (specific Moon-sign relations like 6-8 or 5-9) is the next-heaviest dosha and is handled separately with its own cancellation rules.

Layer 2: Manglik check with cancellation

The second layer is the Manglik check. Manglik (also called Mangal Dosha, Sanskrit: Mars affliction in marriage houses) refers to Mars placed in the 1st, 4th, 7th, 8th or 12th house of the natal chart. The classical reading is that Mars in these houses introduces aggression and conflict into the marriage register. Detailed reading of the dosha itself is at manglik dosha Vedic truth.

The compatibility version of the Manglik check operates in two parts. Part one: identify whether each partner carries Mangal Dosha by checking Mars's house position in their own rashi chart. Part two: check the classical cancellation conditions for any Mangal Dosha that is present. The cancellation conditions: Mars in own-sign (Aries or Scorpio) reduces the dosha materially; Mars in exaltation (Capricorn) reduces the dosha materially; Jupiter conjoined or aspecting Mars introduces benefic mitigation that cancels in many classical schools; both partners past a specific age threshold (different schools place this between 28 and 30) reduces the dosha's effective weight; both partners carrying Manglik produces the symmetric-cancellation reading where the two doshas neutralise each other.

The combined Manglik reading on the pairing. Neither partner Manglik: layer scores green. Only one partner Manglik with classical cancellation conditions applying (own-sign, exaltation, Jupiter aspect, age threshold): layer scores yellow because the dosha is mitigated but not zero. Only one partner Manglik without cancellation: layer scores red because the dosha applies to the pairing without symmetric or structural relief. Both partners Manglik with the symmetric cancellation rule applying and no additional friction: layer scores green. Both partners Manglik without cancellation conditions on either side: layer scores red because the symmetric Mars placement concentrates on the marriage axis from both sides without structural relief.

Score this layer:

Layer 3: 7th-lord cross-matching

The third layer is the 7th-lord cross-matching between the two charts. The 7th lord (saptamesha) is the planet that rules the sign on the cusp of the 7th house. It carries the partnership signal at the structural layer of the chart. The cross-matching check operates by overlaying the two charts: place the partner chart's planet positions onto the chart-holder's house structure and identify where the partner's 7th lord falls. Then do the same in reverse.

What to check. Place chart A and chart B side by side. Note which sign and house each chart's 7th lord occupies in its own chart. Then overlay: where does chart A's 7th lord fall in chart B's house structure? Where does chart B's 7th lord fall in chart A's house structure? The cross-placement determines the marriage signal each partner is bringing into the pairing at the structural layer.

The classical reading walks the cross-placements. The 7th lord of one chart falling into the 1st, 5th, 7th, 9th, 10th or 11th of the other chart is supportive: the marriage signal lands in a kendra (angular house), a trikona (trine house) or an upachaya (growth house) of the partner, indicating that the partnership signal contributes positively to the partner's life structure. The 7th lord falling into the 2nd, 3rd, 4th or 12th is neutral or mildly supportive depending on the specific house and its lord. The 7th lord falling into the 6th, 8th or 12th of the partner is the friction reading: the marriage signal lands in a dusthana of the partner, indicating that the partnership signal carries the friction register of that dusthana into the pairing. Detailed reading of the cross-placement is in the divorce-timing framework at divorce timing Vedic compatibility as the heaviest version of this layer's friction.

Score this layer:

Layer 4: D9 Navamsa overlay

The fourth layer is the D9 Navamsa overlay. The Navamsa (D9) is the 9-fold divisional chart in the Vedic system; each sign of the D1 rashi chart is divided into 9 equal parts of 3 degrees 20 minutes and each part maps to a Navamsa sign. Classical practice treats the D9 as the layer that reveals marriage durability beneath the surface D1 reading. The full single-chart D9 reading is at will my marriage last D9.

The D9 overlay in the 5-layer check runs the previous three layers at the D9 layer. Layer 1 at the D9: the Ashtakuta gun-milan operates on Moon nakshatra, which is the same in D1 and D9 reading (the layer does not duplicate at D9 because Ashtakuta does not depend on house structure). What does carry over at D9: Vargottama Venus (Venus in the same sign in D1 and D9) or Vargottama 7L (the D1 7L occupying the same sign in D9) on either chart strongly supports the durability layer. Layer 2 at the D9: check whether Mars's placement in D9 also triggers Manglik for each partner. A partner who is Manglik in D1 but not in D9 has the dosha mitigated at the durability layer; a partner who is Manglik in D9 carries the dosha through to the durability layer. Layer 3 at the D9: run the 7th-lord cross-matching at the D9 layer by checking where each partner's D9 7L falls in the partner's D9 house structure.

The classical convention is that the D1 and D9 readings should agree for a reliable compatibility prediction. When they agree, the composite holds at both layers. When they disagree, the D9 carries the durability verdict. A pairing with strong D1 compatibility but weak D9 compatibility reads as surface compatibility without underlying durability: the marriage begins well but the durability layer carries unresolved friction. A pairing with weak D1 compatibility but strong D9 compatibility reads as surface friction with deeper durability: the marriage takes more effort to establish but holds at the durability layer.

Layer 5: Mahadasha alignment for the marriage window

The fifth layer is the timing layer. The previous four describe the structural compatibility at the natal-chart layer. Layer 5 checks whether the prospective marriage window falls inside a mahadasha (Sanskrit: major planetary period) alignment that supports marriage on both sides.

What to check. Compute the current mahadasha and antardasha (sub-period) for each partner. Identify the active planet in each. Check whether the active planet is a marriage-supporting planet on each chart. A marriage-supporting planet in this context is one of: the 7th lord, a planet placed in the 7th house, the marriage karaka (Venus for men, Jupiter for women), a planet that aspects the 7th house, a benefic (Jupiter, Venus, well-placed Mercury or waxing Moon) placed in a kendra or trikona or the lagna lord (ruler of the rising sign) when it is well-disposed. Then check whether the two charts have marriage-supporting periods that overlap in the prospective marriage window.

The classical reading walks three timing-window configurations. Both partners simultaneously running marriage-supporting mahadasha or antardasha: strongest configuration, the timing layer fully supports the marriage. One partner in a marriage-supporting period and the other in a neutral period (not actively supporting but not actively obstructing): acceptable configuration, the marriage proceeds without strong timing tailwind but without obstruction. One partner in a marriage-supporting period and the other in a marriage-obstructing period (a malefic dasha that activates the 6th, 8th or 12th lord or a dasha that activates Mangal Dosha or Saturn-Mars friction): friction configuration, the marriage proceeds against a timing-layer headwind. Both partners in marriage-obstructing periods simultaneously: red configuration, the timing layer does not support marrying in this window.

The mahadasha layer is the only one of the five that is window-specific rather than chart-level. The other four are stable structural readings of the natal charts. Mahadasha alignment changes over time. A pairing that scores red on layer 5 in one window may score green on layer 5 in a future window once the mahadasha sequence shifts. The structural layers (1 through 4) do not change; the timing layer does. This is the layer that can be addressed through marriage-window selection rather than through marriage-pair selection.

Reading the 5-layer composite

The composite of the five layer scores is the structural reading. The convention.

The composite weights each layer equally. There is no convention in classical practice that ranks one layer as more important than another for the should-I-marry decision, because each layer reads a different dimension and the dimensions do not substitute for each other. A high Ashtakuta score does not compensate for a 7th-lord cross-placement in a dusthana. A clean D9 overlay does not compensate for both-sides Manglik without cancellation. The layers are read independently and the composite is the simple count.

What the check does not say

The 5-layer check describes the structural compatibility at the chart-layer. Three boundaries to keep in mind.

First, the check does not make the decision. The decision to marry or not marry remains the chart-holders'. The chart-layer describes the structural conditions on which the marriage will be attempted. What is brought to those conditions actively (attention, work, the choice to address friction patterns when they appear, the willingness to accept partner-and-self limits) determines the actual outcome. A green-composite chart can produce a marriage that ends because the partners did not show up to it. A red-composite chart can produce a durable marriage because the partners did the structural work the chart-layer was signalling.

Second, the check is most useful as a structural awareness tool rather than as a verdict. The yellow and red scores point to specific friction patterns that the marriage will need to manage. The actionable use of the check is to read those patterns honestly and decide whether sustained management of those specific frictions is realistic for both partners. The classical practice in red-layer configurations recommends an open conversation about the specific friction patterns each red layer describes before the marriage is finalised.

Third, the check operates on the natal-chart layer of compatibility. It does not read the partnership's contextual conditions: the families, the cultural fit, the financial alignment, the life-stage alignment, the geographic fit. These contextual layers are not in the chart and do not appear in the 5-layer check. A pairing that scores well on the chart-layer can still encounter friction from the contextual layer and a pairing that scores poorly on the chart-layer can still hold if the contextual layer compensates. The chart-layer reading is one input into the decision, not the whole decision.

Computation and method note

Tempora's compatibility computation runs on Swiss Ephemeris (the standard high-precision planetary ephemeris) with the True Pushya Paksha ayanamsa (the sidereal correction system that places the fixed star Pushya at the 0-degree Cancer mark). House cusps follow the Whole Sign system for the Parashari method. Ashtakuta scoring follows the conventional 36-point weighting documented in BPHS Chapter 7. The Manglik check covers the standard five houses (1st, 4th, 7th, 8th, 12th) with cancellation by own-sign, exaltation, Jupiter aspect and the age threshold convention. The D9 overlay uses the standard Parashari D9 algorithm. Mahadasha calculation uses the Vimshottari system (the 120-year mahadasha sequence based on Moon nakshatra at birth), which is the conventional mahadasha system for the Parashari tradition; other dasha systems are documented separately and may produce different timing windows.

Frequently asked questions

Can Vedic astrology tell me if I should marry this person?

Vedic astrology cannot make the decision for you. What it can do is read the structural compatibility of two charts and tell you what the chart-layer says about the marriage's structural conditions. The reading is descriptive, not prescriptive. A five-layer compatibility check covers the major dimensions the classical literature uses. Layer 1 is Ashtakuta gun-milan, the 8-factor scoring from the two Moon nakshatras. Layer 2 is the Manglik (Mars) check on both sides with cancellation conditions. Layer 3 is the 7th-lord cross-matching across the two charts. Layer 4 is the D9 Navamsa overlay for marriage durability. Layer 5 is the mahadasha alignment for the marriage window. Each layer scores green, yellow or red. The composite is the structural reading. Whether to marry is a decision the chart-layer cannot make.

What is the 5-layer Vedic compatibility check?

The 5-layer check is a structured walkthrough of the major classical compatibility dimensions. Layer 1: Ashtakuta gun-milan, the 8-factor scoring from the Moon nakshatras of both partners, producing a score out of 36 with 18 as the minimum acceptable threshold. Layer 2: Manglik (Mars affliction in marriage houses) check on both charts with the classical cancellation conditions (own-sign, exaltation, Jupiter aspect, age threshold, both-sides symmetry). Layer 3: 7th-lord cross-matching, checking the placement of each chart's 7th lord against the partner chart's house structure. Layer 4: D9 Navamsa overlay, the 9-fold divisional chart used for marriage durability that runs the same compatibility checks at the deeper layer. Layer 5: Mahadasha alignment, checking that both partners run a marriage-relevant mahadasha or antardasha during the prospective marriage window. Each layer is scored independently.

What does each green-yellow-red score mean?

Each of the five layers scores independently. Green means the layer supports the marriage at the structural level; the classical reading does not raise friction concerns on this dimension. Yellow means the layer registers structural friction that needs active management; the marriage can hold but the specific friction pattern the layer describes will require sustained attention. Red means the layer registers structural divorce-tier stress on this dimension; the classical reading treats the layer as a serious concern that the rest of the chart will need to compensate for. The composite reading: zero or one red across the five layers is workable with awareness. Two reds is a structural concern that needs more than awareness. Three or more reds across the five layers is the classical signature for a marriage that is structurally unsupported by the chart-layer.

Is the Ashtakuta score the whole compatibility reading?

No. The Ashtakuta gun-milan score is one layer of the compatibility reading and operates only on the Moon nakshatras of the two partners. A high Ashtakuta score does not guarantee marriage durability and a low score does not preclude it. The classical practice uses Ashtakuta as the first screen because it is the easiest layer to compute and produces a single score out of 36 that captures the basic Moon-nakshatra compatibility. The remaining four layers (Manglik, 7th-lord cross-matching, D9 Navamsa overlay, mahadasha alignment) carry equal or greater weight in the full compatibility reading. The popular practice of relying on Ashtakuta alone misses the deeper layers the classical literature treats as more important for marriage durability.

What is the D9 Navamsa overlay and why does it matter?

The D9 Navamsa is the 9-fold divisional chart in the Vedic system. Each sign of the D1 rashi chart is divided into 9 equal parts of 3 degrees 20 minutes and each part maps to a specific Navamsa sign. Classical practice treats the D9 as the layer that reveals marriage durability beneath the surface D1 reading. The D9 Navamsa overlay in the 5-layer check runs the previous three layers (Ashtakuta cross-references, Manglik check and 7th-lord cross-matching) at the D9 layer to see whether the D9 reading agrees with the D1 reading. When the D1 and D9 readings agree, the compatibility prediction is reliable. When they disagree, the D9 carries the durability verdict per the BPHS convention. A high D1 score with a low D9 score indicates surface compatibility without underlying durability; a low D1 with high D9 indicates surface friction with deeper durability.

How does mahadasha alignment work for the marriage window?

Mahadasha alignment is the timing layer of the compatibility check. The natal chart sets the structural compatibility; the mahadasha selects whether the prospective marriage window activates marriage-relevant planets. The check has two parts. Part one: each partner's current and upcoming mahadasha and antardasha are checked for whether the active planet is the 7th lord, the marriage karaka (Venus for men, Jupiter for women), a planet placed in the 7th house, a planet aspecting the 7th or a benefic in a kendra or trikona. Part two: the two partners' active mahadashas and antardashas are checked for whether they activate compatible signatures in the same window. The strongest mahadasha alignment is when both partners run marriage-supporting periods simultaneously and the active planets share a Parashari friendship relation. The weakest is when one partner runs a marriage-supporting window and the other runs an unrelated or hostile-planet window.

What should I do if three or more layers score red?

Three or more red layers across the five-layer check is the classical signature for a marriage that is structurally unsupported by the chart-layer. The reading does not say the marriage cannot work; it says that the structural conditions do not support it by default and that whatever supports it will need to come from outside the chart-layer. The classical practice in this configuration recommends a careful conversation about the specific friction patterns each red layer describes, an honest assessment of whether sustained active management is realistic for both partners, a check on whether timing the marriage to a more supportive mahadasha window changes the composite and consultation with a practitioner who can read the D9 in detail. The decision remains the chart-holders'. The chart-layer describes the structural conditions; it does not enforce the outcome.
