BPHS source guide
Previous birth in Vedic astrology: the Sun–Moon and Drekkana loka method
An answer-first walkthrough of the BPHS Purvayoni rule shown in the source—what to calculate, what not to substitute, and where traditional interpretation ends.
Direct answer
In the BPHS Purvayoni method shown in the source, compare the Sun and Moon and select the stronger luminary. Find that luminary’s sign in the classical D3/Drekkana chart, take the ruler of the D3 sign, and map the ruler: Jupiter to Devaloka; Venus or Moon to Pitrloka; Sun or Mars to Mrityuloka; Mercury or Saturn to Naraka or another lower-realm category in the visible Hindi commentary. This is a traditional Jyotish classification, not proof of reincarnation.
Open the free calculatorThe complete rule in four steps
- 1
Choose the stronger luminary
Compare only the Sun and Moon. The visible passage says to use whichever is stronger; the reel presenter uses Shadbala.
- 2
Find that luminary in D3
Use its natal longitude to calculate the classical Drekkana sign. Do not use D9/Navamsa.
- 3
Take the D3 sign ruler
Identify the ordinary lord of the sign occupied by the selected luminary in D3. Do not substitute the D3 ascendant lord.
- 4
Apply the loka table
Map that D3 sign ruler to the source's four traditional categories shown below.
What does “stronger Sun or Moon” mean?
The visible passage says to use whichever of the Sun and Moon is stronger, but it does not define the comparison method in the excerpt. The reel presenter operationalizes ‘stronger’ through Shadbala.
Complete Shadbala is a sixfold strength framework. It is not interchangeable with one dignity label, one house placement, brightness, or whichever planet merely “feels stronger.” A trustworthy comparison should come from software or an astrologer that calculates the complete method consistently.
Why the calculator asks you to supply this field
Destiny Unfolds does not calculate Shadbala in this public tool because the app's current routine is explicitly simplified. You supply which luminary trusted software reports as stronger; the calculator then performs the D3 and loka steps transparently.
D1 placement, D3 division, D3 sign, and D3 lord are different
The D1 position is the selected luminary's sidereal natal longitude. Its location within the 30-degree D1 sign determines which of three classical Drekkana portions it enters:
1st portion
0°–9°59′59″
Same sign
2nd portion
10°–19°59′59″
5th sign from it
3rd portion
20°–29°59′59″
9th sign from it
After that division produces the D3 sign, take the ruler of that sign. The rule does not ask for the D3 ascendant, the D3 ascendant lord, or a planet merely occupying the natal Drekkana.
The planet-to-loka mapping
Apply this only after finding the ruler of the selected luminary's D3 sign.
| D3 sign ruler | Traditional loka | Plain-language meaning |
|---|---|---|
| Jupiter | Devaloka | A deva or celestial realm |
| Venus or Moon | Pitrloka | The ancestral realm |
| Sun or Mars | Mrityuloka | The mortal or human realm |
| Mercury or Saturn | Naraka / lower-realm group | A lower or inferior realm in the visible Hindi commentary |
The Mercury/Saturn row preserves the visible commentary's source category. It should not be used to shame, frighten, or rank a person's spiritual worth.
Worked example: stronger Sun at 15° Aries
Input
Sun is stronger
D1
Sun at 15° Aries
D3
Leo · 5th from Aries
Mapping
Sun ruler → Mrityuloka
At 15° Aries, the Sun occupies the second ten-degree portion. The fifth sign from Aries is Leo; Leo is ruled by the Sun. The source table therefore gives Mrityuloka, meaning the mortal or human realm in this classification. This demonstrates the arithmetic—it does not verify a literal former identity.
Source and edition limits
A Hindi edition of Brihat Parashara Hora Shastra, page 344, section ‘Purvayoni ka Gyan’ (Knowledge of the Previous Birth), verses 115–116 in the visible edition.
The edition, translator, volume, chapter number, publisher, and ISBN are not visible in the reel, so this page does not invent those bibliographic details.

Can a D3 chart show a previous birth?+
In the BPHS method shown here, the D3 sign occupied by the stronger of the Sun or Moon is used as one step in a traditional loka classification. It does not empirically verify a previous birth or identify a historical person.
Do I use the D3 ascendant lord?+
No. This rule uses the ruler of the D3 sign occupied by the selected stronger luminary. The D3 ascendant, its lord, and the selected luminary are separate factors.
Do I choose the strongest planet in the chart?+
No. Compare only the Sun and Moon. The reel presenter uses Shadbala to decide which of those two is stronger.
Is D3 the same as D9 Navamsa?+
No. D3 is the Drekkana chart, with three divisions per sign. D9 is the Navamsa chart, with nine divisions per sign. This method uses D3.
Does Mrityuloka mean death?+
In this classification, Mrityuloka refers to the mortal or human realm. It is not a prediction of death, lifespan, or danger.
What if Sun and Moon strength are nearly tied?+
Treat the result as uncertain. Recheck birth data and compare complete Shadbala calculations from trusted software before interpreting the D3 mapping.
