Table rules identify Sarvartha Siddhi, Amrita Siddhi, Siddha, Visha, Dagdha, and Pushkara Yogas.

Assurance ​

LevelCurrent statement
Documented and traceableYes — the canonical record includes the process and a worked example.
Regression or reproduction checkedLinked to 2 repository test file(s).
Independently source-supportedNot recorded as independently verified. The disclosed provenance state remains authoritative.

Computation method ​

Method type: decision-table

Evaluate independent weekday-Nakshatra, weekday-Tithi, Tithi-family, and Pushkara conjunction tables and return every matched Yoga in fixed order.

Process ​

  1. Test Sarvartha Siddhi and Amrita Siddhi weekday-Nakshatra tables.
  2. Convert Tithi to its 1-15 Paksha ordinal and test Visha and Dagdha weekday tables.
  3. Map Tithi to Nanda/Bhadra/Jaya/Rikta/Purna and test its Siddha weekday partner.
  4. On Sunday, Tuesday, or Saturday, test the Dvipushkara and Tripushkara Tithi-Nakshatra conjunctions.
  5. Append each match; do not collapse simultaneous Yogas.

Worked example ​

Guruvaram, Shukla Navami, Pushya ​

Inputs

  • Vaaram: Guruvaram
  • Tithi ordinal within Paksha: 9
  • Nakshatra: Pushya

Calculation

  1. Pushya is in Thursday's Sarvartha Siddhi set and is Thursday's Amrita Siddhi Nakshatra.
  2. Thursday's Visha Tithi is 9.
  3. No other configured rule matches these inputs.

Result

  • Sarvartha Siddhi Yoga
  • Amrita Siddhi Yoga
  • Visha Yoga

Evidence class: textual

Locator: No precise locator is registered.

Scope: Special Yogas, Panchaka labels, Khara month, Pitru Paksha, Simha-Stha, Maudhya, Anandadi Yoga, Disha Shoola, Nakshatra Mukha and Panchaka Rahita are separate traditional classifications. The group exists to expose evidence debt and grants no umbrella textual authority; each component needs its own inspected rule table and regional boundary.
