Trikona Dasha System in Brihat Parashara Hora Shastra (BPHS)
1. Significance of Trikona Dasha
Trikona Dasha is a Rashi-based (Sign-based) conditional Dasha system described in Brihat Parashara Hora Shastra (BPHS). The name “Trikona” (meaning “triangle”) highlights its focus on the trinal houses (1st, 5th, and 9th houses), which are considered highly auspicious and represent Dharma (righteousness), knowledge, and fortune.
Applicability Conditions:
- Used when the Ascendant (Lagna) is in a Dual Sign (Gemini, Virgo, Sagittarius, or Pisces).
- Effective for analyzing spiritual growth, higher knowledge, and fortune.
- Helps in understanding career, destiny, and luck-related aspects.
2. Calculation of Trikona Dasha
Trikona Dasha assigns fixed durations to signs, and the sequence follows a pattern based on the trinal influences.
Step-by-Step Calculation
- Identify the Ascendant (Lagna) and confirm that it is in a Dual Sign (Gemini, Virgo, Sagittarius, or Pisces).
- The sequence of Dashas starts from the strongest Trikona house (1st, 5th, or 9th house).
- The order of Dashas follows the trinal sequence of signs.
- The duration of each Mahadasha is based on the strength and house placement of the ruling planet of that sign.
Sequence of Trikona Dasha:
- Starting sign: The sign in which the strongest Trikona house falls.
- Following Dashas: The sequence follows trinal movement (1st, 5th, 9th house signs in progression).
- Duration: Determined by the ruler of the sign and its planetary strength.
3. Structure of Trikona Dasha
Trikona Dasha consists of multiple time divisions:
- Mahadasha (Main period): Governs the broader life trends.
- Antardasha (Sub-period or Bhukti): Adds secondary influences.
- Pratyantar Dasha: Provides finer details of events.
4. Application of Trikona Dasha
Trikona Dasha is widely used for:
- Wealth & Fortune: Influence of 9th and 5th house Dashas.
- Education & Higher Learning: Influence of 5th house Dashas.
- Spiritual Growth & Dharma: Activation of 9th house Dashas.
- Career & Life Path: Effects of 1st house Dashas.
Analysis Methods
- Strength of the Dasha Sign – Determines the outcomes of the period.
- Position of the Dasha Lord – Affects the specific results within the Mahadasha.
- Aspects and Conjunctions – Modify the influences of the Dasha period.
- Transits Correlation – Helps refine predictions by aligning with planetary movements.
5. Special Considerations in Trikona Dasha
A. Role of Benefic vs. Malefic Influences
- Benefic planets (Jupiter, Venus, Mercury, Moon) enhance fortune, wisdom, and prosperity.
- Malefic planets (Mars, Saturn, Rahu, Ketu) can cause challenges but also lead to transformation.
B. Influence of Yogas
- If a sign in the Dasha sequence forms Raj Yoga, the period brings great success.
- Dhana Yogas in Trikona houses indicate financial growth.
C. Transition Between Mahadashas
- Major changes occur when moving between Dharma houses (1st, 5th, 9th) and Kendra or Dusthana houses.
Conclusion
Trikona Dasha, as explained in Brihat Parashara Hora Shastra, is a Rashi-based predictive system that emphasizes the strength of Trikona houses (1st, 5th, and 9th houses). It provides deep insights into wealth, education, career, and spiritual progress, making it an essential tool for understanding life’s fortune and destiny.
