Meaning
Dhanu means "the bow", and the Brihat Jataka draws its archer as "a man who in his lower parts is a horse" (I.5, Iyer 1885). Its other name is Toukshika, one of those Iyer notes as Greek.
It is a dual sign, odd and masculine, and its triangle with Mesha and Simha faces east. The text counts it a night sign that rises by its feet. Guru rules it and has its moolatrikona here; no graha is exalted or debilitated in it in the Brihat Jataka.
Our chart's text for a Dhanu lagna describes an idealistic, principled bearing drawn to learning and dharma, aiming high, and suggests matching lofty aims with practical steps.
Dhanu opens with Mula and the third round of the Vimshottari lords; the sample person on our system page has Shukra and Shani here, in Purva Ashadha.
In the chart
Dhanu is the ninth rashi, 240° to 270° of the sidereal zodiac, and it holds Mula, Purva Ashadha and the first pada of Uttara Ashadha. In the whole-sign houses of the chart, the rashi of the lagna is the first bhava and each rashi after it the next, so Dhanu is the first bhava for a Dhanu lagna, the seventh for a Mithuna lagna, and so on round the twelve.
Its navamsas begin with Mesha: the nine parts of 3°20′ run Mesha, Vrishabha, Mithuna, Karka, Simha, Kanya, Tula, Vrishchika and Dhanu, as the Brihat Jataka's rule gives them, the movable rashis starting from themselves, the fixed from the ninth and the dual from the fifth. In 2026 the rashi covers about 24°13′ Sagittarius to 24°13′ Capricorn of the tropical zodiac, by the Lahiri measure, so a planet in tropical Sagittarius is often in Vrishchika here; another ayanamsa would move the edges by up to about 2.5°.

How the schools read it
- The Brihat Jataka (Varahamihira, 6th century; Iyer 1885)
- "A man who in his lower parts is a horse"; called Toukshika; dual, odd and masculine; its triangle faces east; a night sign rising by its feet; lord Jupiter, whose moolatrikona it is.
- Modern Jyotisha
- A dual fire rashi ruled by Guru, its element and quality grouped as in the Western triplicities.
- Western tropical astrology
- Sagittarius, the same twelfth of the circle counted from the March equinox, about 24° ahead in 2026.
- Other ayanamsas
- Raman's about 1.5° smaller than Lahiri's, Krishnamurti's about 5′ smaller, Fagan-Bradley's about 53′ larger: a placement near an edge can change rashi.
- The chart forms
- South Indian: Dhanu has its own fixed box; North Indian: the boxes are the bhavas and the rashi's number, 9, moves with the lagna.
- EsoTerrier
- Our chart's text for a Dhanu lagna: "With Dhanu as lagna, a dual fire rashi ruled by Guru, the person is often idealistic, principled and drawn to learning and dharma. The archer, part human and part horse, aims high, and matching lofty aims with practical steps helps Guru's wisdom take root." Our words.
Claims about it
-
The sidereal rashi shows the sky as it really is: it is the constellation of that name.
falseWhat the record shows: Both zodiacs measure the same positions from different starting points. A rashi is an equal 30° division counted from a point set by the ayanamsa, not the constellation of the same name.
-
The Lahiri ayanamsa is accepted everywhere.
falseWhat the record shows: Lahiri is India's national standard and by far the most used, but the KP school, B. V. Raman's followers and Western siderealists use other values, up to about 2.5° apart; a placement near a rashi's edge can change rashi between them.
-
The sidereal signs sit about 24° behind the tropical ones whichever ayanamsa is used.
disputedWhat the record shows: True for Lahiri (about 24°13′ in 2026) and close for Krishnamurti; Raman's is about 1.5° less and Fagan-Bradley's about 0°53′ more.
