Sthira Dasha System in Brihat Parashara Hora Shastra (BPHS)
1. Significance of Sthira Dasha
Sthira Dasha is a Rashi-based (Sign-based) Dasha system described in Brihat Parashara Hora Shastra (BPHS). Unlike Nakshatra-based Dashas like Vimshottari, Sthira Dasha focuses on fixed signs and their lordships to determine life events. It is particularly useful for analyzing fixed and unchanging aspects of life, such as destiny, wealth, and career stability.
Applicability Conditions:
- Primarily used in Jaimini astrology, focusing on Rashi influences.
- Best suited for analyzing material and tangible aspects of life.
- Applicable to all charts but works effectively when Ascendant is in a fixed sign (Taurus, Leo, Scorpio, Aquarius).
2. Calculation of Sthira Dasha
Sthira Dasha assigns fixed durations to zodiac signs, and its sequence is determined based on specific rules:
Step-by-Step Calculation
- Identify the strongest fixed sign (Sthira Rashi) in the horoscope.
- The sequence of Dashas starts from the strongest fixed sign, followed by others in a fixed pattern.
- The duration of each Mahadasha is calculated based on the house placement of its lord in the natal chart.
- The order of Dashas follows the placement of fixed signs first, then movable and dual signs in a structured manner.
Sequence of Sthira Dasha:
- Fixed signs (Taurus, Leo, Scorpio, Aquarius) are prioritized.
- Movable signs (Aries, Cancer, Libra, Capricorn) come next.
- Dual signs (Gemini, Virgo, Sagittarius, Pisces) follow last.
The duration of each sign’s Mahadasha varies based on its lord’s house placement.
3. Structure of Sthira Dasha
Sthira Dasha consists of different time divisions:
- Mahadasha (Main period) – The ruling sign for a longer duration.
- Antardasha (Sub-period or Bhukti) – The influence of a secondary sign within a Mahadasha.
- Pratyantar Dasha – Further divisions for detailed event predictions.
4. Application of Sthira Dasha
Sthira Dasha is used for:
- Career Growth & Stability – Influence of the 10th house sign during its Mahadasha.
- Wealth & Financial Stability – Activation of the 2nd and 11th house signs.
- Marriage & Relationships – Effects of the 7th house sign.
- Health & Longevity – Influence of the 6th, 8th, and 12th house signs.
Analysis Methods
- Strength of the Dasha Rashi – Determines whether the period will be beneficial or challenging.
- Position of Dasha Lord – Affects the overall impact of the period.
- Aspects and Conjunctions – Modify the effects of the Dasha period.
- Transits Correlation – Helps refine event timing.
5. Special Considerations in Sthira Dasha
A. Role of Benefic vs. Malefic Signs
- Benefic signs (ruled by Jupiter, Venus, Mercury, Moon) bring positive results.
- Malefic signs (ruled by Mars, Saturn, Rahu, Ketu) may bring challenges unless well-placed.
B. Influence of Yogas
- If a sign forms Raj Yoga or Dhana Yoga, it brings success and prosperity.
- Vipreet Raj Yoga may indicate difficulties followed by unexpected gains.
C. Transition Between Mahadashas
- Major life changes occur when shifting from one Mahadasha to another, particularly when moving between benefic and malefic signs.
Conclusion Sthira Dasha, as explained in Brihat Parashara Hora Shastra, is a Rashi-based predictive system that helps astrologers analyze life events with a focus on fixed, stable aspects such as career, wealth, and longevity. By studying the placement of signs, their lords, and transits, astrologers can make precise predictions regarding an individual’s long-term success and challenges.
