How Yava Yoga forms
This is the exact condition the check above applies.
| Condition | Requirement |
|---|---|
| The grahas | All in kendras |
| Malefics | Only in the 1st and 7th |
| Benefics | Only in the 4th and 10th |
| Its mirror | Reverse the two and you have Vajra Yoga instead |
| How often it occurs | Did not occur in a 398-chart sample |
The barley grain is narrow at both ends and full in the middle — which is exactly what the classical result describes.
What Sārāvalī says Yava Yoga gives
Sārāvalī gives observance of fasts and religious rules, intent on auspicious acts, happy in the middle of life, liberal, and possessed of lasting wealth.
Every clause is favourable, which makes Yava the more fortunate half of the Vajra pair. The benefics hold home and career — the houses that build a life — while the malefics sit on the self and the partner, where the tradition reads them as hardening rather than destroying.
The middle of life is the notable detail, and it is the precise complement of Vajra's beginning-and-end. Between them the two yogas divide a lifetime.
Ākṛti yogas — the shape the grahas make
Yava is the other half of that pair, and the more fortunate of the two.
We measured it rather than guessed, and Yava did not occur once in a sample of 398 charts. That follows from what it asks — malefics in 1 and 7, benefics in 4 and 10. — 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.
