How Hala Yoga forms
This is the exact condition the check above applies.
| Condition | Requirement |
|---|---|
| The grahas | All seven, Sun through Saturn |
| The houses | One trinal set — 2/6/10, 3/7/11, or 4/8/12 |
| Excluded | The 1/5/9 set. That configuration is Śṛṅgāṭaka, not Hala. |
| How often it occurs | Did not occur in a 398-chart sample |
The distinction from Śṛṅgāṭaka is the whole of it: same trinal shape, different trine.
What Sārāvalī says Hala Yoga gives
Sārāvalī gives eating in plenty while remaining indigent, an agricultural occupation, subjection to grief, an emotional temperament, abandonment by relatives and friends, and life in service.
The plough works ground that belongs to someone else. That is the reading: productive labour whose product does not accumulate to the labourer, which is exactly what "eats in plenty, yet indigent" describes.
It is the least fortunate of the trinal yogas, and the reason is the missing 1/5/9 — no self, no merit, no fortune in the occupied set.
Ākṛti yogas — the shape the grahas make
Hala takes a trinal set that excludes the Lagna, which is the whole difference between it and Śṛṅgāṭaka.
We measured it rather than guessed, and Hala did not occur once in a sample of 398 charts. That follows from what it asks — all seven grahas in mutual trines, avoiding the Lagna. — 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.
