The three, with what Sārāvalī gives each
Four signs of each modality, and all seven grahas must fall inside them.
| Modality | Yoga | Signs | What Sārāvalī gives |
|---|---|---|---|
| Movable | Rajju — the rope | Aries, Cancer, Libra, Capricorn | Fond of wandering, attractive in appearance, earns money in foreign countries — and cruel, mischievously disposed. |
| Fixed | Musala — the pestle | Taurus, Leo, Scorpio, Aquarius | Honour, wealth and wisdom, attached to duty, liked by those in authority, famous, steady-minded and bold. The only unqualified result of the three. |
| Dual | Nala — the reed | Gemini, Virgo, Sagittarius, Pisces | An uneven physique — some limbs long and some short — gathers money, skilful, helpful to relatives, attractive in appearance. |
The three modalities read almost exactly as their names suggest: movable gives motion and foreign earning, fixed gives steadiness and standing, dual gives adaptability and unevenness. It is the most direct mapping from structure to temperament anywhere in the Nābhasa chapter.
How often an Āśraya yoga actually forms
Rarely. Each modality covers four of the twelve signs, so all seven grahas landing inside one is roughly a one-in-seven-hundred proposition — and none of the three occurred once in a sample of 398 charts measured through our engine.
That is before the cancellation rule is applied. Because every chart also carries a Saṅkhyā yoga by definition, a strict reading of the chapter means an Āśraya yoga is always superseded and never delivers its own effects at all.
Most lineages soften that, treating the Saṅkhyā yogas as a separate scheme and applying the cancellation only against Ākṛti and Dala yogas. This page reports the Āśraya yoga when the modality condition is met and states the cancellation plainly rather than resolving a dispute the tradition has not settled.
Āśraya yogas — and the rule that cancels them
The three Āśraya yogas depend only on the modality of the signs occupied — all movable, all fixed, or all dual. They carry a condition no other class does, stated plainly in the chapter: an Āśraya yoga gives its effects only when no other Nābhasa yoga is present. If any Ākṛti, Saṅkhyā or Dala yoga is also formed, that one prevails and the Āśraya lapses. In practice an Āśraya yoga is almost always accompanied, so it is read as a background tone rather than as a verdict.
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.
