Brihat Parashara Hora Shastra
Attributed to Maharshi ParasharaThe foundation of the Parashari system: houses, divisional charts, yogas and the Vimshottari dasha.
Parashari Jyotish · tested, not just told
Classical Jyotish in its full depth, interpreted with scientific discipline.
Birth chart, divisional charts, dashas and transits are read together, as the classical authors intended, and every judgement is checked against the evidence of your own life.
The methodology
Like a lotus, a chart reveals itself layer by layer
The classical texts describe a horoscope in layers, and their sutras often pull in different directions. A promise in the birth chart must be confirmed in the divisional charts, supported by planetary strength, opened by a dasha and triggered by a transit. Only when the layers agree does a judgement stand.
- Layer 1BPHS · Lahiri ayanamsa
The birth chart
Exact sidereal positions, ascendant, houses and nakshatras, calculated to the minute of birth, including historical time-zone corrections that many tools miss.
- Layer 2BPHS · Vargas
Divisional charts
The Navamsa for marriage and inner strength, the Dashamsa for career. What the birth chart promises must be confirmed here before it is relied on.
- Layer 3Laghu Parashari · Phaladeepika
Strength and lordship
Dignity, combustion and the functional nature each planet takes on for your ascendant. Yogas are identified with their cancellations, so a combination is never read in isolation.
- Layer 4BPHS · Vimshottari
Timing through dashas
Vimshottari periods, sub-periods and sub-sub-periods decide when a promise can open. A strong yoga stays dormant until its period arrives.
- Layer 5Phaladeepika · Gochara
Transits as triggers
Slow-moving planets, above all Jupiter and Saturn, activate what the dasha has made possible and help narrow a window to months.
- Layer 6Laghu Parashari
Weighing the contradictions
Where sutras disagree, they are weighed by the priorities the texts themselves set out: lordship over natural character, confirmation across charts, strength over mere placement.
Then, the test
Before anything is forecast, the combined reading is checked against four to six dated events from your own life. Only the judgements that hold on your past are carried forward into your future, and the report shows which ones they are.
Sources
Ancient wisdom, at its source
Every sutra is traced to its text, chapter and verse, so the ancient wisdom behind a reading can be checked, not taken on trust.
Laghu Parashari
Also known as Jataka ChandrikaA compact text on how house lordship makes a planet helpful or harmful, and how dashas deliver results.

From the Sutras
What has held up so far
Early results, graded by how consistently each sutra holds. Next in testing: marriage and relationship sutras.
| ID | Sutra | Source | Charts | Result |
|---|---|---|---|---|
| S-001 | Sign exchange activates both planets' houses in either planet's dasha | Phaladeepika, Yogas | In progress | Promising |
| S-002 | Saturn in the 4th brings change of residence in its own dasha | BPHS, Dasha phala | In progress | Promising |
| S-003 | Moon in the 12th brings relocation in its antardasha | General signification | In progress | Supporting |
How this compares
Why not a free app, a consultation, or a chatbot?
Each has its place. Here is what this approach does differently.
| Free chart apps | Per-minute consultation apps | General AI chatbots | LotusAstro reports | |
|---|---|---|---|---|
| Precise calculation | Yes | Usually | May estimate positions rather than calculate them | Yes, checked against reference software |
| Tested on your past first | No | Rarely | Only if you know to ask | Every report |
| Rules cited to the classical texts | Rarely | Varies by astrologer | Citations can be invented | Text, chapter and verse |
| Specific timing | General period summaries | Varies | General unless closely steered | Dated windows to the sub-period |
| Misses shown openly | Rarely | Rarely | Rarely | Yes |
| How you pay | Free, often with paid upgrades or remedies | By the minute | Subscription, plus your time | One fixed price, no upselling |
| Checked by a practitioner | No | Yes | No | Yes, before delivery |
A capable chatbot can do much of this if you know exactly what to ask and can spot its errors. A LotusAstro report is designed to do it every time, with the calculations verified and the reasoning shown.
