Lost Horoscopy (Nashta Jataka)
Nashta Jataka is used when exact birth data is missing, uncertain, or the record is lost. BPHS Chapter 78 presents a prashna-based reconstruction method that starts from the moment the query is asked and then narrows the likely birth pattern through structured rules.
When to Use This Method
- Birth time is unknown or approximate.
- Birth register is unavailable or disputed among family records.
- Chart events do not match existing birth-time assumptions.
- Rectification needs a traditional Vedic prashna anchor.
Inputs Required
| Input | Purpose |
|---|---|
| Prashna Lagna | Primary frame for reconstructive logic. |
| Nakshatra and Pada of query moment | Refines timing and life-pattern inference. |
| Karaka grahas | Maps known life events to planetary significators. |
| Major life events | Used to triangulate and validate candidate times. |
Step-by-Step Procedure (Paraphrased)
- Cast the prashna chart for the exact question time and place.
- Note lagna, moon position, nakshatra, and strong angular influences.
- Derive candidate birth-lagna windows using prashna-derived correspondences.
- Check candidate charts against known milestones: education, marriage, career shifts, health events.
- Use karaka alignment and dasha plausibility to reject weak candidates.
- Converge on the birth-time interval with the highest event fit and repeatability.
- Finalize only after re-testing with at least 3-5 independent life events.
For event triangulation workflows, see KP Birth Time Rectification and the Vedic use-case framing in the dasa roadmap notes.
