Durudhura Yoga
Durudhura requires qualifying planets on both the 2nd and 12th sides of the Moon.
The engine does not infer Durudhura from “many planets around the Moon” vaguely. It separately tests the 2nd and 12th sign positions.
At least one qualifying planet must pass on each side.
This rule is taught beside Sunapha and Anapha because all three come from the same Moon-relative structure in Brihat Jataka 13.3 and Phaladeepika 6.5.
Treat every Yoga as a rule audit. Convert the Yoga name into explicit conditions, identify the planets/houses involved, and mark each condition true or false. A name should never be produced before its conditions have been checked.
Formation and strength are different questions. After a Yoga forms, dignity, combustion, functional role, relevant Vargas and timing can change how prominently it is traditionally read; the existence check itself should remain transparent.
How to read it
- Read the exact rule profile.
- List every required condition.
- Check each condition against the chart.
- Mark formed only when the profile’s conditions pass.
- Assess condition/strength/timing separately.
Key points
- Yoga detection is a condition check, not a keyword search.
- Different texts can define similarly named Yogas differently.
- A formed Yoga is not a guaranteed event.
Do not combine conditions from different source profiles and then call the result “classical.”
Apply this lesson to a chart
- Open Yoga Lab and choose one Yoga.
- Read every pass/fail condition before looking at the final status.
- Explain in your own words why the Yoga formed or failed.
