Sthira Dasha is a third sign-based system, less widely taught than Chara or Narayana, but used by advanced practitioners for timing refinement. "Sthira" means "fixed."
The principle: Certain signs are "fixed" in their nature (Taurus, Leo, Scorpio, Aquarius), and Sthira Dasha sequences through signs or houses in a fixed, unchanging order (usually Lagna, 2nd, 3rd, ... 12th house).
Duration for each Sthira dasha is derived from the natural ruler of that sign's domain (e.g., Sthira 1st dasha = 12 years, 2nd dasha = 8 years, etc., following classical planetary periods).
Use case: When Chara and Narayana predict the same general period but differ on exact timing, Sthira may provide a tiebreaker. Some charts also show strong Sthira dasha correspondences with events.
Limitation: Sthira is less standardized than Chara/Narayana; different schools teach different duration lists. This course uses the most common form (12, 8, 5, 10, 7, 18, 16, 19, 17 years for houses 1-9, then repeat), but acknowledge that variation exists.
Advanced note: Sthira Dasha can also be derived from Karakamsha (the house of AK) rather than Lagna, creating another layer of detail.
The lesson briefly covers Sthira without deep computation (calculator support is optional). Focus on understanding when Sthira is used and how it refines Chara/Narayana predictions.
Fixed by design. Sthira means fixed. Unlike Chara and Narayana, where period lengths derive from each sign's lord, Sthira Dasha assigns each sign a fixed duration. This makes it simpler to compute and less sensitive to the chart's particulars.
Its role. Sthira Dasha is generally used as a third opinion. When Chara and Narayana disagree about a period, Sthira offers an independent reading that may break the tie. It is rarely used as a chart's primary timing system.
The methodological caution. Consulting a third dasha only when the first two disagree is defensible. Consulting a fourth, fifth and sixth until one agrees with a desired conclusion is not. Decide in advance how many systems you will consult and in what order.
What to do when all three disagree. Genuine three-way disagreement is a meaningful result: it indicates the timing is not well determined by the chart. Reporting that is more useful, and more honest, than picking the most agreeable of the three.
