D7 Saptamsha
Use seven equal parts, starting from the natal sign in odd signs and the 7th from it in even signs.
Each Saptamsha is 30°/7. Phaladeepika 3.6 says odd signs are counted from the sign itself and even signs from the 7th sign onward.
After choosing that starting sign, each successive Saptamsha advances one zodiac sign.
The app exposes the exact part number so a student can audit the mapping instead of trusting a hidden D7 result.
Each Varga is a deterministic mapping of the natal longitude using its own subdivision rule. The resulting Varga degree is a derived coordinate inside that divisional chart, not a new astronomical observation.
Use a Varga only for the topic it is meant to refine and always start from the natal D1 promise. More charts do not automatically produce more accuracy if the reader mixes their roles.
How to read it
- Start from the exact D1 longitude.
- Apply the Varga’s subdivision rule.
- Identify Varga sign, degree and house.
- Compare with D1 without replacing it.
- Use the relevant topic-specific practicum for synthesis.
Key points
- Varga placement is derived, not a separate sky measurement.
- Different Vargas answer different refinement questions.
- Birth-time/degree errors can propagate into divisional charts.
Do not stack many Vargas into one conclusion without first deciding what question each chart is supposed to answer.
Apply this lesson to a chart
- Open Varga Lab and choose the Varga from this lesson.
- Pick one planet and record D1 → Varga sign/house.
- Explain what changed structurally without judging it as good or bad.
