How Śakaṭa Yoga forms
This is the exact condition the check above applies.
| Condition | Requirement |
|---|---|
| The grahas | All seven, Sun through Saturn |
| The houses | Only the 1st and the 7th |
| Empty | The other ten houses |
| How often it occurs | Did not occur in a 398-chart sample |
Two different yogas share this name. The Nābhasa Śakaṭa is this one. The far more commonly discussed Śakaṭa Yoga is the Moon in the 6th, 8th or 12th from Jupiter, which is a completely separate combination with its own cancellation rule.
What Sārāvalī says Śakaṭa Yoga gives
Sārāvalī gives an unrelieved list: troubled by disease, a bad marriage, dull-witted, living by pulling carts, poor, and without relatives or friends.
The image is exact. A cart has two wheels and travels only where it is pulled; a chart with everything on the 1st–7th axis has no third point of support. The 4th and 10th are empty, which removes both home and standing.
The severity of the classical language reflects a world in which cart-pulling was the floor of the labour market. The structural claim underneath — a life with only two points of contact and no elevation — is what carries over.
Ākṛti yogas — the shape the grahas make
Śakaṭa is one of two yogas confining all seven grahas to a single axis.
We measured it rather than guessed, and Śakaṭa did not occur once in a sample of 398 charts. That follows from what it asks — all seven grahas in the 1st and 7th only. — which the seven grahas almost never satisfy together. A "not present" result here is close to certain, and carries no bad news.
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.
