How Chatra 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 7th — 7, 8, 9, 10, 11, 12, 1 |
| Empty | Houses 2 through 6 must contain none of the seven |
| How often it occurs | 10.1% of charts in our sample |
A chatra is the parasol held over a king — protection extended outward and downward, which is precisely what the results describe.
What Sārāvalī says Chatra Yoga gives
Sārāvalī gives the kindest description of the four: helps his own people, kind, liberal, dear to those in authority, very intelligent — and happy in boyhood and again at the end of life.
That last detail is unusually specific and worth keeping. Chatra promises happiness at the two ends and is silent about the middle, which reads as a life whose difficulty is concentrated in its working years.
The shape supports the reading. The run covers the 7th through the 1st — others, crisis, dharma, action, gain, loss, and finally the self — so the chart is oriented outward across almost its whole span, and returns to the self only at the very end of the sequence.
Ākṛti yogas — the shape the grahas make
Chatra is the run anchored on the 7th, and the only one of the four whose result is wholly favourable.
We measured it rather than guessed: across a sample of 398 charts, Chatra formed in 10.1% 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.
