Mastering Ashtakavarga Part 16: Longevity Calculation — Method A (Bhinnashtakavarga)
A comprehensive exploration of B.V. Raman's Ashtakavarga System of Prediction, bringing ancient mathematical astrology into modern practice with clarity and precision.
Part 16 of 20 • Longevity Determination • Topics: Ayurdaya, Rasi Gunakara, Graha Gunakara, Sodya Pinda, Haranas
We now reach one of the most profound applications of Ashtakavarga — the determination of longevity (Ayurdaya). Classical astrology mentions 32 different methods for calculating lifespan, including Ashtakavargayu, Jeevasarmayu, Pindayu, Naisargikayu, and Amsayu. B.V. Raman presents two practical methods in this chapter — Method A (based on Bhinnashtakavarga) and Method B (based on Sarvashtakavarga). This article focuses on Method A.
The method involves calculating Rasi Pinda (zodiacal product), Graha Pinda (planetary product), combining them into Sodya Pinda, applying Haranas (reductions), and converting from lunar to solar years. While mathematically elegant, Raman himself cautions that these methods should not be relied upon as foolproof — actual longevity often varies significantly from calculated values.
"In our humble view, mathematical methods of longevity determination cannot be relied upon safely. While Amsayu has yielded correct results in a number of cases, longevity determined according to Ashtakavarga has not been found satisfactory in many cases."
Ethical Note: Longevity predictions should be approached with extreme caution. These methods are presented for educational purposes and to understand classical techniques. Always use judgment, compassion, and ethical restraint when discussing lifespan with clients.
Rasi Gunakara (Zodiacal Factors)
Each of the 12 zodiac signs has been assigned a constant numerical factor called Rasi Gunakara (zodiacal multiplier). These values are universal constants, identical for all horoscopes.
| Sign (Rasi) | Zodiacal Factor | Sign (Rasi) | Zodiacal Factor |
|---|---|---|---|
| Aries | 7 | Libra | 7 |
| Taurus | 10 | Scorpio | 8 |
| Gemini | 8 | Sagittarius | 9 |
| Cancer | 4 | Capricorn | 5 |
| Leo | 10 | Aquarius | 11 |
| Virgo | 5 | Pisces | 12 |
Calculation Process
- Take the after-reduction bindus (benefic points) from each planet's Bhinnashtakavarga (after both Trikona and Ekadhipatya reductions)
- Multiply the bindus in each sign by that sign's Rasi Gunakara
- Sum all 12 products to get the Rasi Pinda (zodiacal product) for that planet
Worked Example: Sun's Rasi Pinda in Standard Horoscope
| Sign (Rasi) | Bindus (After Reductions) | × | Zodiacal Factor | = | Zodiacal Product |
|---|---|---|---|---|---|
| Aries | 0 | × | 7 | = | 0 |
| Taurus | 3 | × | 10 | = | 30 |
| Gemini | 2 | × | 8 | = | 16 |
| Cancer | 0 | × | 4 | = | 0 |
| Leo | 0 | × | 10 | = | 0 |
| Virgo | 4 | × | 5 | = | 20 |
| Libra | 0 | × | 7 | = | 0 |
| Scorpio | 1 | × | 8 | = | 8 |
| Sagittarius | 0 | × | 9 | = | 0 |
| Capricorn | 0 | × | 5 | = | 0 |
| Aquarius | 2 | × | 11 | = | 22 |
| Pisces | 0 | × | 12 | = | 0 |
| Total Rasi Pinda (Sun) | 96 | ||||
Rasi Pindas for All Planets (Standard Horoscope)
| Planet | Rasi Pinda |
|---|---|
| Sun | 96 |
| Moon | 80 |
| Mars | 126 |
| Mercury | 97 |
| Jupiter | 79 |
| Venus | 66 |
| Saturn | 170 |
Graha Gunakara (Planetary Factors)
Just as each sign has a multiplier, each planet also has a constant numerical factor called Graha Gunakara (planetary multiplier). These values are also universal constants.
| Planet (Graha) | Planetary Factor |
|---|---|
| Sun | 5 |
| Moon | 5 |
| Mars | 8 |
| Mercury | 5 |
| Jupiter | 10 |
| Venus | 7 |
| Saturn | 5 |
Calculation Process
- For each of the 7 planets in the horoscope, note which sign they occupy
- From the planet's own Bhinnashtakavarga (after reductions), find the bindus in that sign
- Multiply those bindus by the planet's Graha Gunakara
- Do this for all 7 planets, then sum the 7 products to get the Graha Pinda (planetary product) for that planet's Ashtakavarga
Worked Example: Sun's Graha Pinda in Standard Horoscope
In the Standard Horoscope: Sun in Virgo, Moon in Aquarius, Mars in Scorpio, Mercury in Libra, Jupiter in Gemini, Venus in Virgo, Saturn in Leo.
| Planet | Occupies Sign | Bindus in That Sign (from Sun's Ashtakavarga) | × | Planetary Factor | = | Planetary Product |
|---|---|---|---|---|---|---|
| Sun | Virgo | 4 | × | 5 | = | 20 |
| Moon | Aquarius | 2 | × | 5 | = | 10 |
| Mars | Scorpio | 1 | × | 8 | = | 8 |
| Mercury | Libra | 0 | × | 5 | = | 0 |
| Jupiter | Gemini | 2 | × | 10 | = | 20 |
| Venus | Virgo | 4 | × | 7 | = | 28 |
| Saturn | Leo | 0 | × | 5 | = | 0 |
| Total Graha Pinda (Sun) | 86 | |||||
Graha Pindas for All Planets (Standard Horoscope)
| Planet | Graha Pinda |
|---|---|

| Saturn | 42 |
Sodya Pinda and Gross Longevity
The Sodya Pinda is the sum of Rasi Pinda and Graha Pinda for each planet. This combined figure represents the planet's total longevity contribution before applying reductions.
Formula for Gross Longevity
Gross Longevity (years) = (Sodya Pinda × 7) ÷ 27
If the result exceeds 27 years, subtract 27 to bring it within range.
Worked Example: Sun's Gross Longevity
Rasi Pinda (Sun): 96
Graha Pinda (Sun): 86
Sodya Pinda (Sun): 96 + 86 = 182
Gross Longevity = (182 × 7) ÷ 27 = 1274 ÷ 27 = 47.20 years
Since 47.20 > 27, we subtract 27: 47.20 - 27 = 20.20 years
Gross Longevity for All Planets (Standard Horoscope)
| Planet | Rasi Pinda | + | Graha Pinda | = | Sodya Pinda | ×7÷27 | Gross Years |
|---|---|---|---|---|---|---|---|
| Sun | 96 | + | 86 | = | 182 | → | 20.20 |
| Moon | 80 | + | 20 | = | 100 | → | 26.00 |
| Mars | 126 | + | 71 | = | 197 | → | 24.00 |
| Mercury | 97 | + | 61 | = | 158 | → | 14.00 |
| Jupiter | 79 | + | 45 | = | 124 | → | 5.00 |
| Venus | 66 | + | 0 | = | 66 | → | 15.80 |
| Saturn | 170 | + | 42 | = | 212 | → | 12.00 |
| Total Gross Longevity | 117.00 years | ||||||
This 117 years is the gross longevity before applying any reductions (Haranas).
Haranas (Reductions)
The gross longevity must be reduced based on various planetary afflictions. These reductions are called Haranas. There are six types of reductions:
(a) Conjunction
If more than one planet occupies the same sign, reduce that planet's term by half (1/2).
(b) Debilitation/Combustion
If a planet is debilitated or combust, reduce by half (1/2).
(c) Enemy Sign
If a planet is in the sign of an enemy, reduce by one-third (1/3).
(d) Malefic in Visible Half
If a malefic planet is in the visible half (houses 7-12), apply graduated reductions:
12th house = full term
11th house = 1/2
10th house = 1/3
9th house = 1/4
8th house = 1/5
7th house = 1/6
Benefics lose half of what malefics do.
(e) Planetary War
If a planet suffers defeat in Graha Yuddha (planetary war), reduce by one-third (1/3).
(f) Eclipse
If the Sun or Moon is of unusual appearance (as in eclipse), reduce by one-third (1/3).
Important Rule: When the same planet is subject to multiple reductions, apply only the highest reduction (not cumulative).
Applying Haranas to Standard Horoscope
In the Standard Horoscope:
- Sun: Subject to (a) — in conjunction with Venus in Virgo → reduce by 1/2
- Moon: No afflictions → no reduction
- Mars: Subject to (d) — malefic in 12th house (visible half) → reduce by 1/2
- Mercury: Subject to (d) — benefic in 11th house (visible half) → reduce by 1/6
- Jupiter: No afflictions → no reduction
- Venus: Subject to (a) conjunction, (b) combustion, (d) benefic in visible half → highest is 1/2
- Saturn: Subject to (c) — in enemy sign Leo → reduce by 1/3
| Planet | Gross Years | Reduction Type | Fraction | Net Years |
|---|---|---|---|---|
| Sun | 20.20 | (a) | 1/2 | 10.10 |
| Moon | 26.00 | — | — | 26.00 |
| Mars | 24.00 | (d) | 1/2 | 12.00 |
| Mercury | 14.00 | (d) | 1/6 | 11.67 |
| Jupiter | 5.00 | — | — | 5.00 |
| Venus | 15.80 | (a), (b), (d) | 1/2 | 7.90 |
| Saturn | 12.00 | (c) | 1/3 | 8.00 |
| Total Net Longevity (Chandramana) | 80.67 years | |||
Lunar to Solar Conversion
The final step is converting from Chandramana (lunar measure) to Sauramana (solar measure), as our calendar years are solar.
Solar Longevity = (Lunar Longevity × 324) ÷ 365
This conversion factor accounts for the difference between the lunar and solar year cycles.
Final Calculation for Standard Horoscope
Net Longevity (Chandramana): 80.67 years
Solar Conversion: (80.67 × 324) ÷ 365 = 26,137.08 ÷ 365
Final Longevity (Sauramana): 71.6 years
Raman's Honest Assessment
B.V. Raman, unlike many classical authors, provides an honest and cautionary note about the reliability of Ashtakavarga-based longevity methods. This intellectual honesty is one of the hallmarks of his scholarship.
"In our humble view, mathematical methods of longevity determination cannot be relied upon safely. While Amsayu has yielded correct results in a number of cases, longevity determined according to Ashtakavarga has not been found satisfactory in many cases."
Raman notes that ancient authorities themselves were not agreed on which of the 32 methods were foolproof and universally applicable. While he presents the methods in detail (for completeness and education), he explicitly states that actual longevity often varies significantly from calculated values.
Modern Perspective: These methods should be studied for historical understanding and as part of learning classical techniques. They should not be used as definitive predictive tools for lifespan. Always exercise extreme caution, ethical judgment, and compassion when discussing longevity with clients.
