A rāśi daśā is not a planet daśā
Vimśottarī and its relatives are graha daśās: each period belongs to a planet, and you read the planet. The Jaimini systems on this page are rāśi daśās: each period belongs to a sign, and for the length of that period the sign functions as the Lagna. You read the whole chart from it.
That difference changes what the technique can do. A planet daśā tells you which significator is active. A sign daśā tells you where you are standing — which house of your chart has become the first house, and therefore what every other house now means relative to it. During a period whose sign is the 6th from your Lagna, the 6th house is your new self, and the ordinary reading of the chart reorganises around that.
The practical consequence is that rāśi daśās are read by counting houses from the daśā sign. The 10th from it is the career of that period, the 7th its relationships, the 4th its home. This is why they pair so well with Vimśottarī rather than competing with it: one names the actor, the other names the stage.
The Śrī Lagna — what it is and how it is found
The Śrī Lagna is a computed point, not a planet or a house. It is derived from two things: the Lagna, and how far the Moon has travelled into its nakṣatra.
Take the fraction of the Moon's nakṣatra that has elapsed — a Moon exactly one quarter of the way through its star gives 0.25. Multiply that fraction by the full zodiac, and add the result to the Lagna's longitude. Where you land is the Śrī Lagna.
The construction says something. The Lagna is the self and the Moon's nakṣatra is the seed of the Vimśottarī daśā — the thread of time running through the life. Śrī Lagna sits at the intersection: the point where the self meets its own unfolding, which is where prosperity is held to enter.
Because the calculation depends on the Lagna's exact degree, the Śrī Lagna moves quickly. A birth-time error of a few minutes will shift it, and a large one will move it into a different sign and change the entire daśā sequence.
How the sequence runs
The first period belongs to the sign of the Śrī Lagna. From there the sequence moves in kendrādi order — through the angles from that sign, then the succedents, then the cadents — with the direction set by whether the seed sign is odd or even.
Period lengths follow the same principle as the other rāśi daśās: the position of the sign's lord relative to the sign decides the count, with adjustments for dignity. A second cycle with complementary durations completes the 144-year span.
This kendrādi movement is the structural signature of Sudāśā and the reason it feels different in practice from Nārāyaṇa daśā. Blessings, in this scheme, move through the structural houses of a chart rather than walking sign by sign.
What kind of blessing — the forms of Lakṣmī
A Sudāśā period does not simply bring "good fortune". The character of the blessing is read from what occupies the daśā sign and what that sign signifies from the Lagna. The classical scheme names the forms.
| Form | What she gives |
|---|---|
| Gajalakṣmī | Vehicles, conveyances, movement |
| Dhanalakṣmī | Money and material wealth |
| Santānalakṣmī | Children and progeny |
| Rājalakṣmī | Power, position and authority |
| Mokṣalakṣmī | Liberation — spiritual advancement |
The reading is made from the occupants and significations of the daśā sign. A period whose sign holds Ketu, for instance, tends to bring the mokṣa form: matters of spirituality come easily during it, while worldly gain may not. The blessing is real either way; what varies is what it is a blessing of.
Reading Sudāśā with Nārāyaṇa daśā
This is the whole point of the technique, and it is the reason to compute both rather than one.
Line up the two sequences. A stretch where a strong Nārāyaṇa period is followed by a strong Sudāśā period on the same house or significator is the classical picture of effort rewarded — work done in the first, fruit collected in the second, usually with a lag.
A strong Nārāyaṇa period with a poor Sudāśā running alongside describes the opposite and more painful pattern: real, sustained work that does not pay while it is being done. People in that configuration often conclude they are doing the wrong thing. Frequently they are doing the right thing early.
And a strong Sudāśā with a weak Nārāyaṇa is fortune arriving without effort — inheritance, an unexpected opening, a benefit from someone else's work. It is pleasant and it is not something to build a plan on.
Why Sudāśā is the most time-sensitive of the three
Because the Śrī Lagna is built from the Lagna's exact degree plus the fraction of its nakṣatra the Moon has covered, and both move. The Lagna advances about a degree every four minutes; the Moon covers a full nakṣatra in roughly a day, so its fraction changes measurably within an hour. The two errors compound, and the Śrī Lagna can shift a sign on a birth time out by as little as ten to fifteen minutes — at which point the whole sequence and every date in it changes. Of the three rāśi daśās here, this is the one to rectify for first.
How this is computed
Positions come from an astronomical ephemeris, converted to the sidereal zodiac on the Lahiri (Citrapakṣa) ayanāṁśa and computed by our own Parāśara engine — no pre-written results, and no language model anywhere near a number. Where the classical texts disagree, this page names the convention we follow instead of quietly picking one.
