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.
What Nārāyaṇa daśā shows — effort, not fruit
The name is the key to the technique. Nārāyaṇa here stands for the active self, the part of a person that does things. So this daśā tracks what you are actually working on and where your effort goes — not what you receive for it.
That distinction matters because it explains the technique's most common apparent failure. A period can be a Nārāyaṇa daśā of great activity and produce nothing visible, and a person reading it as a prediction of results will call it wrong. It was not a prediction of results. It said where the work would be, and the work was there.
For results, the companion technique is Sudāśā, which tracks the progression of the Śrī Lagna and shows where blessings land. Read together, the two answer a question neither answers alone: when the effort goes in, and when the fruit arrives — which are very often not the same period.
How the sequence begins — the seed sign
The first period is not simply the Lagna. It is decided by a strength comparison.
- The candidates
- The Lagna and the 7th house from it. The daśā begins from whichever of the two is stronger.
- How strength is judged
- By the classical Jaimini rules of sign strength — the number and nature of planets occupying each sign, the placement and dignity of its lord, an exalted planet in the sign, and aspects. Our engine applies these in order and falls back to the Lagna when they tie.
- In a divisional chart
- The same comparison is made between the divisional Lagna and the 7th from it, using that chart's own placements. This is why a Nārāyaṇa daśā cast in the D-10 can start from a completely different sign than the one cast in the D-1.
Which way the sequence moves
The order of signs after the seed is fixed by the seed's modality, and its direction by the 9th from it.
- Base direction
- Look at the 9th sign from the seed. If it is odd-footed the sequence runs forward (zodiacal); if even-footed, backward.
- Movable seed
- The sequence steps one sign at a time in that direction.
- Fixed seed
- The sequence jumps to the 6th sign each time — a five-sign step in the chosen direction.
- Dual seed
- The sequence moves trinally: three signs in trine, then to the 10th from the base, then its trines, and so on through all twelve.
- Two overrides
- Saturn occupying the seed sign forces the sequence forward regardless of the base rule. Ketu occupying the seed reverses whatever the base direction would have been. Where both are present, Saturn takes precedence in this implementation.
How long each period lasts
A sign's daśā length is decided by where its lord sits relative to it. Count from the daśā sign to the sign occupied by its lord — forward if the daśā sign is odd-footed, backward if even-footed — and the period is that count minus one, in years.
Two adjustments follow. If the lord occupies the daśā sign itself, the period is a full 12 years rather than zero. And the lord's dignity shifts the count: exalted adds a year, debilitated subtracts one, held within one and twelve.
Because twelve signs then run through a second cycle with complementary durations, the whole sequence covers 144 years — enough that every chart's meaningful periods fall within the first cycle and part of the second.
A note on variants: several traditions handle the exaltation and debilitation adjustment differently, and some omit it. If another program gives you period lengths a year off from these, that adjustment is almost certainly the reason.
Casting it in a divisional chart — where the technique earns its keep
This is the part that most tools omit entirely, and it is arguably the most useful thing about Nārāyaṇa daśā. The same daśā can be cast in any varga, and when it is, it times that varga's subject specifically.
Cast in the D-10, it times career: the periods when professional effort concentrates, changes direction, or is rewarded. Cast in the D-9, it times matters of dharma and marriage. Cast in the D-2, it times financial activity. Cast in the D-24, it times education — and because educational events are precisely dated, that combination is one of the better instruments for testing a proposed birth time.
Read the divisional Nārāyaṇa daśā by counting houses from the daśā sign within that chart. In a D-10 Nārāyaṇa daśā, a period whose sign is the 10th from the D-10 Lagna is a period of career elevation; one whose sign is the 6th from it is a period of service, subordination or conflict at work.
Use the varga selector above the sequence to switch charts. The dates change because the seed sign changes with the chart.
How to read a Nārāyaṇa period
Treat the daśā sign as the Lagna and read outward. What occupies it, what aspects it by rāśi dṛṣṭi, and what its lord is doing are the three things that set the tone. Then count: the 10th from the daśā sign for activity and standing, the 7th for partnership, the 4th for home and peace, the 6th for conflict.
Note which house of the natal chart the daśā sign actually is. A period in a sign that is your natal 8th house will be a period of upheaval whatever else it contains; one in your natal 9th tends toward fortune and guidance. The daśā sign's natal house is the background against which the period's own reading plays out.
Then cross-check against Vimśottarī. Where a Nārāyaṇa period and a Vimśottarī period point at the same house or the same significator, the indication is genuinely reinforced — the two systems are independent enough that agreement between them means something. Where they disagree, Vimśottarī usually describes what is felt and Nārāyaṇa what is done.
How birth-time error moves a Nārāyaṇa sequence
In steps rather than smoothly, which makes it deceptive. The seed sign, the direction and every period length are computed from whole signs, so a chart cast ten minutes either side of the recorded time usually gives an identical sequence — and then, at some point, the Lagna crosses a sign boundary and the entire sequence changes at once. The exposure is therefore concentrated at the edges: a Lagna in the middle of its sign is safe on a rough time, a Lagna in the first or last degree is not. Casting the daśā in a divisional chart raises the risk sharply, since the D-10 Lagna changes every twelve minutes and the D-9 Lagna every thirteen.
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.
