How Nauka Yoga forms
This is the exact condition the check above applies.
| Condition | Requirement |
|---|---|
| The grahas | All seven, Sun through Saturn |
| The houses | The seven continuous houses from the Lagna — 1, 2, 3, 4, 5, 6, 7 |
| Empty | Houses 8 through 12 must contain none of the seven |
| How often it occurs | 9.8% of charts in our sample |
Nauka is one of four yogas built the same way — Nauka from the Lagna, Koota from the 4th, Chatra from the 7th, Chāpa from the 10th. The four angles each anchor one.
What Sārāvalī says Nauka Yoga gives
Sārāvalī gives livelihood through water, many gains, considerable fame, and a person who is pleased with themselves — and then adds, in the same breath, that they are mean and stingy.
The boat is the image: everything the chart has is loaded into one half of the wheel and carried. What that produces is accumulation without release — gains arrive and are held rather than circulated, which is exactly what the "stingy" clause is describing.
The water connection is meant literally in the source and can be read more widely now: trades that move things, that cross distances, or that depend on what flows.
Ākṛti yogas — the shape the grahas make
Nauka is the first of the four continuous-run yogas, and the only one anchored on the Lagna itself.
We measured it rather than guessed: across a sample of 398 charts, Nauka formed in 9.8% of them.
The twenty Ākṛti yogas are named for the figure the seven grahas trace across the houses — a boat, a parasol, a bow, a lotus. Sārāvalī gives the class its own result before the individual ones: a person with any Ākṛti yoga is satisfied with their own fortune, earns through authority, is dear to those in power, and is famous. The individual yoga then says what kind of person that is.
Two things true of every Nābhasa yoga
They run continuously — Sārāvalī says the Nābhasa yogas are "effective at all times independent of Daśās", which sets them apart from almost every other yoga in Jyotiṣa. And they constrain all seven grahas at once, so most charts carry only a few and a "not present" result is the ordinary answer.
How this check works
Your chart is computed from an astronomical ephemeris on the Lahiri (Citrapakṣa) ayanāṁśa, and the formation rule stated on this page is tested against it directly — the same rule, not a paraphrase. Where the classical texts disagree about a condition, the page names the reading we follow.
