Jathagam Guide - Part 6A: How to Read Jathagam

ஜாதகம் வழிகாட்டி - பாகம் 6A: ஜாதகம் படிப்பது எப்படி

Welcome to Part 6A - where everything comes together! This is the practical guide that teaches you to actually read and analyze a Jathagam chart, plus complete marriage compatibility (பொருத்தம்) analysis.


Understanding the Jathagam Chart - ஜாதக அட்டவணை

Tamil/South Indian Chart Format

Two Main Chart Formats:

  1. South Indian Chart (Tamil/Kerala style) - Diamond/Square shape, houses are fixed
  2. North Indian Chart - Square with houses that rotate

We’ll focus on South Indian style (most common in Tamil Nadu, Kerala, Karnataka, Andhra).

South Indian Chart Layout:

Key Points:

Houses are FIXED positions (don’t rotate)

  • House 1 (Lagna) is always top-center
  • Houses proceed counter-clockwise
  • Each box represents one house

Planets and signs rotate based on birth time

  • Lagna (Ascendant) sign goes in box #1
  • Other signs follow in order
  • Planets are placed in their respective sign boxes

STEP 1: Identify Lagna and Moon

Why Start Here?

  • Lagna (Ascendant): Your body, personality, overall life path
  • Moon (Chandra): Your mind, emotions, mental state

What to Note:

A. Lagna Analysis:

AspectWhat to CheckSignificance
Lagna SignWhich Rasi in 1st house?Basic personality traits
Lagna LordWhich planet rules Lagna?Primary life direction
Lagna Lord PositionWhich house is Lagna lord in?Where energy flows
Planets in LagnaAny planets in 1st house?Direct personality influence
Aspects on LagnaWhich planets aspect 1st?External influences

Example from Sample Chart:

  • Lagna: Pisces (மீனம்) → Spiritual, dreamy, compassionate nature
  • Lagna Lord: Jupiter (rules Pisces)
  • Jupiter Position: 1st house itself (in Pisces, own sign) → VERY STRONG!
  • Result: Person has strong Jupiterian qualities - wisdom, ethics, teaching ability

B. Moon Analysis:

AspectWhat to CheckSignificance
Moon Sign (Rasi)Which Rasi has Moon?Emotional nature
NakshatraWhich Nakshatra?Detailed personality, Dasha start
Moon StrengthWaxing/Waning? House?Mental strength
Planets with MoonConjunction?Emotional influences

Example from Sample Chart:

  • Moon Sign: Taurus (ரிஷபம்) → Stable emotions, materialistic, patient
  • Nakshatra: Rohini (ரோகிணி) → Beautiful, artistic, sensual
  • Moon in: 3rd house → Courageous mind, communication skills
  • With Venus: Moon-Venus combo → Artistic talents, pleasant nature

STEP 2: Check Planetary Strengths

Quick Strength Assessment:

A. Exaltation/Debilitation Check:

PlanetIn Sample ChartSignStatusEffect
Sun5th houseCancerNeutralChildren, creativity average
Moon3rd houseTaurusExalted!Strong mind, stable emotions
Mars9th houseScorpioOwn SignStrong fortune, courage
Mercury1st housePiscesDebilitatedWeak communication, confused thinking
Jupiter1st housePiscesOwn SignVery strong wisdom, ethics
Venus3rd houseTaurusOwn SignStrong comforts, arts
Saturn12th houseAquariusOwn SignStrong spirituality, expenses

Analysis:

  • 3 planets in own signs (Jupiter, Venus, Mars, Saturn) → Strong chart!
  • 1 exalted (Moon) → Blessed mental state
  • 1 debilitated (Mercury) → Needs remedy for communication

B. Kendra/Trikona Placement:

Planets in Kendras (1,4,7,10) or Trikonas (1,5,9) are strengthened.

Sample Chart:

  • 1st (Kendra + Trikona): Jupiter, Mercury → Jupiter very powerful
  • 5th (Trikona): Sun → Good for children
  • 9th (Trikona): Mars → Excellent fortune

Result: Many planets in good houses → Blessed chart!


STEP 3: Analyze Key Houses

Priority Houses to Check:

House 1 (Lagna - Self):

  • Already analyzed above
  • Jupiter in own sign → Strong personality

House 9 (Fortune - பாக்கியம்):

  • Sign: Scorpio
  • Planet: Mars (in own sign)
  • 9th lord: Mars (strong)
  • Analysis: Excellent fortune! Mars in own sign in trikona = prosperity, father’s blessings

House 10 (Career - கர்மம்):

  • Sign: Sagittarius
  • Planet: Ketu
  • 10th lord: Jupiter (in 1st house)
  • Analysis: Mixed - Ketu in 10th can cause career confusion, but Jupiter as 10th lord in 1st is excellent (Dharma Karmadhipati Yoga!)

House 7 (Marriage - கலத்திரம்):

  • Sign: Virgo
  • No planets
  • 7th lord: Mercury (debilitated in 1st)
  • Analysis: Weak 7th lord = marriage delays or issues with spouse communication

House 2 (Wealth - தனம்):

  • Sign: Aries
  • No planets
  • 2nd lord: Mars (in 9th, own sign)
  • Analysis: Good wealth! 2nd lord strong in fortune house

House 11 (Gains - லாபம்):

  • Sign: Capricorn
  • No planets
  • 11th lord: Saturn (in 12th, own sign)
  • Analysis: Saturn (11th lord) in 12th = expenses, but in own sign = balanced, foreign gains

STEP 4: Check for Doshas

Dosha Checklist:

A. Chevvai Dosham Check:

  • Mars position from Lagna: 9th house ❌ (not in 1,2,4,7,8,12)
  • Mars position from Moon: Mars in Scorpio, Moon in Taurus = Mars in 7th from Moon ✅
  • Result: Partial Chevvai Dosham (from Moon only)
  • Remedy needed: Yes, but mild (marrying someone with same dosha cancels it)

B. Kaal Sarpa Check:

  • Draw Rahu-Ketu axis: Rahu in Leo (6th), Ketu in Sagittarius (10th)
  • All planets between? Let’s check:
    • Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn
    • Sun in Cancer (5th) ✅
    • Moon in Taurus (3rd) ✅
    • Mars in Scorpio (9th) ✅
    • Mercury in Pisces (1st) ✅
    • Jupiter in Pisces (1st) ✅
    • Venus in Taurus (3rd) ✅
    • Saturn in Aquarius (12th) ✅
  • All planets between Rahu (6th) and Ketu (10th) going counter-clockwise!
  • Result: Partial Kaal Sarpa Dosha (Mahapadma type - Rahu in 6th)

C. 7½ Sani Check:

  • Moon in Taurus
  • Saturn currently where? (Need current date transit - not birth chart)
  • This is a transit dosha, check separately

D. Pitru Dosha Check:

  • Sun with Rahu/Ketu? No
  • Sun in 5th (Cancer) - own house, no affliction
  • No Pitru Dosha

STEP 5: Identify Yogas

Yoga Checklist:

A. Raj Yoga Check:

Kendra-Trikona Combinations:

  • Lagna lord (Jupiter) in 1st house (Kendra + Trikona) ✅
  • 9th lord (Mars) in 9th house (Trikona) ✅
  • 5th lord (Moon) in 3rd house ❌
  • 10th lord (Jupiter - same as Lagna lord) ✅

Finding: Jupiter is both 1st and 10th lord = Dharma Karmadhipati Yoga!

Additional: Jupiter in own sign in Lagna = Hamsa Yoga (Panch Mahapurusha)!

B. Dhana Yoga Check:

  • 2nd lord: Mars
  • 11th lord: Saturn
  • Position: Mars in 9th, Saturn in 12th
  • Not together, but 2nd lord in 9th = Dhana Yoga (wealth through fortune)

C. Gajakesari Yoga Check:

  • Moon in Taurus (3rd house)
  • Jupiter from Moon? Jupiter in Pisces, Moon in Taurus = 11th from Moon
  • No Gajakesari (Jupiter not in Kendra from Moon)

D. Other Yogas:

  • Moon-Venus conjunction in 3rd = Artistic talents, pleasant speech
  • Mars in own sign in 9th = Fortune through courage, father’s blessings
  • Venus in own sign in 3rd = Communication through arts

STEP 6: Current Dasha Period

Birth Nakshatra: Rohini (Moon Dasha)

Dasha Sequence from Birth:

  1. Moon Dasha balance: ~8 years remaining (born in Moon Dasha)
  2. Mars Dasha: Age 8-15 (7 years)
  3. Rahu Dasha: Age 15-33 (18 years)
  4. Jupiter Dasha: Age 33-49 (16 years)
  5. Saturn Dasha: Age 49-68 (19 years)

Current Age (2026): 31 years old

Current Dasha: Rahu Mahadasha (in progress, year 16 of 18)

Analysis:

  • Rahu in 6th house (enemies, diseases, debts)
  • Challenging period - obstacles, health issues, enemies
  • But Rahu in Mahapadma Kaal Sarpa type
  • Upcoming: Jupiter Dasha at age 33 (2 years away) → GOLDEN PERIOD!
    • Jupiter is Lagna lord, own sign, Hamsa Yoga
    • Best 16 years of life ahead!

STEP 7: Synthesize Findings

Overall Chart Assessment:

Strengths (பலம்):

  • Hamsa Yoga - Great personality, wisdom, ethics
  • Dharma Karmadhipati Yoga - Career + fortune combined
  • Moon exalted - Strong mind, emotional stability
  • Mars in 9th in own sign - Excellent fortune
  • Multiple planets in own signs - Strong chart
  • Upcoming Jupiter Dasha - Best years ahead

Weaknesses (குறைகள்):

  • Mercury debilitated - Communication issues, indecisive
  • Partial Chevvai Dosham - Marriage needs matching
  • Partial Kaal Sarpa - Some obstacles, but manageable
  • Ketu in 10th - Career confusion, frequent job changes
  • Current Rahu Dasha - Challenging period until age 33

Life Prediction:

  • Personality: Wise, ethical, spiritual, artistic, but confused communication
  • Career: Teaching, spiritual work, counseling (Jupiter + Pisces influence), but job changes due to Ketu in 10th
  • Wealth: Good through fortune (Mars in 9th), steady accumulation
  • Marriage: Delays due to weak 7th lord and Chevvai Dosham, but will happen. Match with person having same dosha
  • Health: Generally good, Moon strong. Watch Rahu in 6th - stomach issues possible
  • Best Period: Age 33-49 (Jupiter Dasha) - peak success, wealth, recognition
  • Current Phase: Struggling (Rahu), but breakthrough coming at 33!

Remedies:

  • Mercury: Emerald/green clothes, Budha mantra, Wednesday fasting
  • Rahu: Hessonite, Rahu remedies for 2 more years
  • Chevvai: Match with partner having same dosha, or Kuja Shanti before marriage

MARRIAGE COMPATIBILITY - திருமண பொருத்தம்

Understanding Porutham System

Porutham (பொருத்தம்) = Compatibility in Tamil

Why Marriage Matching is Important:

  • Marriage is lifelong partnership
  • Compatibility ensures:
    • Harmony between husband-wife
    • Children’s well-being
    • Family prosperity
    • Mutual respect and love
    • Longevity of both partners

10 Poruthams System: Tamil astrology uses 10 different compatibility tests based on the couple’s birth Nakshatras (stars).

Scoring:

  • Total possible: 10 Poruthams
  • Minimum acceptable: 6 Poruthams (some say 5)
  • Ideal: 8+ Poruthams
  • Perfect match (all 10): Rare!

Why Should Male Have More Bhavas (Poruthams) Than Female?

In traditional Tamil/Vedic astrology, there’s an important principle:

“மணமகனுக்கு பாவம் அதிகம் இருக்க வேண்டும்” “Manamaganukkku Baavam Adhigam Irukka Vendum” “The groom should have more Bhavas (positive factors) than the bride”

Traditional Explanation:

1. Husband as Karaka (Significator):

  • In Vedic astrology, husband is the Karaka (primary significator) for wife’s well-being
  • Wife’s chart derives strength from husband’s chart
  • A strong husband’s chart provides:
    • Financial security → 2nd & 11th house strength
    • Family protection → 4th house strength
    • Children’s welfare → 5th house strength
    • Long married life → 7th house strength

2. Wife’s Chart Reflects Husband:

  • 7th house in wife’s chart = Husband’s overall strength
  • If husband has:
    • More Bhavas → More positive factors → Stronger support for wife
    • Weaker chart → Wife may face struggles even with good Porutham

3. Stree Deergha Porutham (Wife’s Longevity):

  • This Porutham specifically checks:
    • Boy’s Nakshatra to Girl’s Nakshatra distance
    • Should be 13 or more positions for wife’s long life
    • If boy’s Nakshatra is “stronger” (more advanced), it protects the girl

4. Karmic Protection Theory:

  • Traditional belief: Male’s stronger karma provides “umbrella protection” for family
  • If male has more positive Bhavas:
    • Family faces fewer obstacles
    • Children have better upbringing
    • Wife enjoys better health and prosperity

Modern Interpretation:

1. Balanced Strength, Not Dominance:

  • It’s not about male “superiority”
  • It’s about balanced strength in the partnership
  • Male having more Bhavas means:
    • He brings more stability to the union
    • Can support wife during her challenges
    • Acts as protective force during difficult times

2. Practical Life Factors:

  • Traditionally, males were primary earners
  • More Bhavas indicated:
    • Better career prospects (10th house)
    • Wealth generation ability (2nd, 11th house)
    • Leadership qualities (1st, 10th house)
  • This ensured family’s financial stability

3. Complementary Strengths:

  • It doesn’t mean female’s chart should be weak
  • Both should have individual strength
  • But male having “more” Bhavas creates:
    • Yang energy (active, protective)
    • Balances Yin energy (receptive, nurturing) of female
    • Creates harmonious equilibrium

What Does “More Bhavas” Mean Practically?

In Porutham Context:

  • If girl’s Porutham score = 7/10
  • Boy’s Porutham score should be = 7/10 or higher (ideally 8/10)
  • NOT lower than girl’s score

In Chart Strength:

  • Boy should have:
    • Stronger Lagna (ascendant)
    • Better placed Jupiter (wisdom, prosperity)
    • Strong 7th house (marriage house)
    • Good 9th house (fortune, dharma)
    • Beneficial yogas (Raj Yoga, Dhana Yoga)

Example:

  • Girl: Rohini Nakshatra, moderate chart strength
  • Boy Option 1: Weak Nakshatra, poor planetary positions → Not recommended (even if Porutham matches)
  • Boy Option 2: Strong Nakshatra, good Jupiter, beneficial yogas → Recommended

What If Female Has Stronger Chart?

Modern Considerations:

1. Career-Oriented Women:

  • If woman is highly educated, career-focused
  • Her strong chart indicates:
    • Independent earning capacity
    • Leadership abilities
    • Self-sufficiency
  • This is NOT negative!

2. Partnership Model:

  • In modern times, marriage is equal partnership
  • Both should have individual strength
  • What matters is:
    • Mutual respect
    • Complementary skills
    • Supportive partnership

3. Adjusted Interpretation:

  • If female has stronger career indicators (10th, 11th house)
  • Male should have:
    • Emotional strength (Moon well-placed)
    • Supportive nature (Venus, 7th house strong)
    • Flexible mindset (Mercury well-placed)
  • This creates modern balanced marriage

4. Check for Specific Factors:

  • Even if female chart is stronger overall:
    • Ensure Rajju Porutham matches (no death risk)
    • Ensure Stree Deergha Porutham matches (longevity)
    • Boy should NOT have severe malefic doshas (Kaal Sarpa, severe Chevvai)
    • Boy’s 7th house should be strong (good husband qualities)

Traditional Concerns to Address:

1. “Stree Balam” (Wife’s Overpowering Strength):

  • Traditional fear: Too strong female chart may “overpower” husband
  • Believed to cause:
    • Husband’s career struggles
    • Health issues for husband
    • Family disharmony

Reality Check:

  • This is outdated patriarchal thinking
  • A successful, strong woman does NOT harm her husband
  • Modern astrology focuses on complementary strengths

2. Remedies for “Strong Female Chart”:

  • If traditional family is concerned:
    • Perform joint pujas for harmony
    • Wear matching gemstones (his: Ruby/Jupiter stone, hers: Pearl/Venus stone)
    • Ensure both charts have good 7th house (mutual respect)
    • Check Upapada Lagna (relationship karma) compatibility

Final Recommendation:

Traditional Guideline:

  • Boy should have equal or more positive Bhavas/Poruthams than girl
  • Ensures traditional “protection” dynamic

Modern Approach:

  • Both should have individually strong charts
  • Focus on complementary strengths, not competition
  • Ensure critical Poruthams match (Rajju, Stree Deergha, Vedha)
  • Check for mutual respect indicators in both charts:
    • Both have good 7th house
    • Both have well-placed Venus (love, harmony)
    • No severe doshas in either chart

Best Practice:

  1. Calculate Porutham score (aim for 6+/10)
  2. Check individual chart strength of both
  3. If girl has stronger chart:
    • Ensure boy has no malefic doshas
    • Boy should have good 7th house (supportive husband)
    • Both should have spiritual compatibility (9th house)
  4. Consult experienced astrologer for nuanced reading

Remember:

  • Astrology is guidance, not absolute
  • Mutual love, respect, and understanding matter more than chart calculations
  • Many successful marriages exist despite “unfavorable” astrological combinations
  • Use astrology as one factor, not the only decision-maker

THE 10 PORUTHAMS IN DETAIL

1. Dina Porutham (தின பொருத்தம்) - Daily/Health Compatibility

What it Checks: Basic health, well-being, and day-to-day harmony

How to Calculate:

  1. Count nakshatras from boy’s star to girl’s star (including boy’s)
  2. Divide by 9
  3. Check remainder

Matching Remainders: 2, 4, 6, 8, or 0

Non-Matching: 1, 3, 5, 7

Example:

  • Boy: Rohini (4th Nakshatra)
  • Girl: Anuradha (17th Nakshatra)
  • Distance: 17 - 4 + 1 = 14
  • 14 ÷ 9 = Remainder 5
  • Result: No Match ✗

Alternative Simple Method: Distance from boy to girl should be: 2, 4, 6, 8, 9, 11, 13, 15, 17, 18, 20, 22, 24, or 26

Importance: Medium - Affects daily health and routine harmony


2. Gana Porutham (கண பொருத்தம்) - Temperament Compatibility

Porutham Scoring Example

Sample Match:

  • Boy: Rohini Nakshatra (Taurus Rasi)
  • Girl: Uttara Phalguni Nakshatra (Leo Rasi)

Let’s Calculate:

PoruthamBoyGirlAnalysisMatch?Points
1. DinaRohini (4)U.Phalguni (12)Distance: 9 → 9÷9=01
2. GanaManushyaManushyaSame1
3. YoniSerpentCowNeutral~0.5
4. RasiTaurus (2)Leo (5)4th position1
5. RasiyathipathiVenusSunNeutral~0.5

8. VashyaChatushpadaVanacharaDifferent0
9. Mahendra4→129 positionsNot 4,7,10,13…0
10. Stree Deergha4→129 positionsLess than 130

Total Score: 6/10Borderline acceptable

Critical Analysis:

  • Rajju: Different ✓ → Good (no death risk)
  • Stree Deergha: Failed ✗ → Concern for wife’s longevity
  • Overall: 6/10 is minimum acceptable, but Stree Deergha failure is serious

Recommendation:

  • Can proceed but with caution
  • Perform remedies for Stree Deergha
  • Ensure wife has strong chart (check separately)
  • Consider consulting expert astrologer

When to Proceed Despite Low Porutham

Exceptions and Overrides:

1. Same Nakshatra Match (நட்சத்திர ஒற்றுமை):

  • If both have same Nakshatra but different padas → Many poruthams auto-match
  • Generally considered very good

2. Kuja Dosha Cancellation:

  • If both have Chevvai Dosham → Cancels the dosha
  • Can overlook 1-2 missing poruthams

3. Strong Individual Charts:

  • If both charts have strong yogas (Raj Yoga, Dhana Yoga)
  • Success despite low porutham possible

4. Lagna-Based Compatibility:

  • Some astrologers also check Lagna (Ascendant) compatibility
  • If Lagnas are compatible → Can override nakshatra porutham

5. Love Marriage (காதல் திருமணம்):

  • If couple is already in love and committed
  • Minimum 5/10 poruthams acceptable
  • But Rajju and Stree Deergha must match!

6. Age Factor:

  • If marrying after age 28 (Mars maturity)
  • Some doshas reduce in strength

7. Remedies Performed:

  • If elaborate Porutham Dosha Nivaran Pujas done
  • Can proceed with 5-6/10 score

Modern vs Traditional Approach

Traditional (பாரம்பரியம்):

  • Strict adherence to all 10 poruthams
  • Minimum 8/10 required
  • Rajju and Stree Deergha are non-negotiable
  • Family elders decide
  • Arranged marriage based on horoscope first

Modern (நவீனம்):

  • Minimum 5-6/10 acceptable
  • Love marriages may proceed with lower score
  • Emphasis on individual chart strength
  • Rajju still important, but can be remedied
  • Personal compatibility interviews also conducted
  • Horoscope is one factor, not the only factor

Balanced Approach (சமநிலை):

  • Use porutham as a guideline, not absolute rule
  • Must-haves: Rajju different, Stree Deergha pass, minimum 5/10
  • Nice-to-haves: 7-8/10 poruthams
  • Consider individual charts (yogas, doshas)
  • Meet the person, assess actual compatibility
  • If genuinely in love and committed, can proceed with remedies
  • Consult expert astrologer for final verdict
