How Vajra Yoga forms
This is the exact condition the check above applies.
| Condition | Requirement |
|---|---|
| The grahas | All in kendras |
| Benefics | Only in the 1st and 7th |
| Malefics | Only in the 4th and 10th |
| Its mirror | Reverse the two and you have Yava Yoga instead |
| How often it occurs | Did not occur in a 398-chart sample |
Vajra and Yava are the same configuration with the benefic and malefic pairs swapped, and their results differ sharply — which makes them a clean demonstration that placement, not merely presence, decides a yoga.
What Sārāvalī says Vajra Yoga gives
Sārāvalī gives happiness at the beginning and end of life, boldness, beauty and freedom from sickness — and then, without softening it, unfortunate and hostile to his own people.
The split matches the shape. Benefics on the horizontal axis — the self and the partner — give the health, the looks and the personal happiness. Malefics on the vertical axis — home and career — put the difficulty into the family and the standing.
The "happy at the beginning and end" clause is the same two-ended pattern Chatra carries, and again the middle of life is left unaddressed.
Ākṛti yogas — the shape the grahas make
Vajra is one half of a matched pair; its twin Yava is the same four houses with the sides swapped.
We measured it rather than guessed, and Vajra did not occur once in a sample of 398 charts. That follows from what it asks — benefics in 1 and 7, malefics 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.
