Twelve rashis, one fixed order
Rashi means 'heap' — a 30-degree heap of the ecliptic. The twelve run in a fixed circle: Mesha (Aries), Vrishabha (Taurus), Mithuna (Gemini), Karka (Cancer), Simha (Leo), Kanya (Virgo), Tula (Libra), Vrischika (Scorpio), Dhanu (Sagittarius), Makara (Capricorn), Kumbha (Aquarius), Meena (Pisces). After Meena, Mesha again. The order never varies.
Sign number 8, counting Mesha as 1? Vrischika — always.
Each rashi wears a picture
The symbols, in the same order: Ram, Bull, Twins, Crab, Lion, Maiden, Scales, Scorpion, Archer, Sea-goat (a crocodile in some traditions), Water-bearer, Fishes. Most names simply mean their picture — Simha is Sanskrit for lion, Meena for fish. The image is a memory hook, not a personality verdict. Verdicts come later.
Makara's symbol is the one beginners misfile: a sea-goat or crocodile, not a plain goat.
Sun and Moon take one throne each
The Sun and Moon are the royals of the graha court, and royals do not divide their attention. Each rules exactly one rashi, and the two sit side by side at the zodiac's heart: the Moon rules Karka (Cancer), the Sun rules Simha (Leo). Every other lordship radiates outward from this royal pair.
Cancer and Leo — signs 4 and 5 — are the hinge of the whole ownership map.
Five planets fan out from the throne
From the royal pair, walk outward in both directions at once. Each of the five planets takes the next sign on each side, in order of distance from the Sun: Mercury first, then Venus, Mars, Jupiter, Saturn. One planet, two signs — a matched pair flanking the royals symmetrically.
One step out: Mercury gets Mithuna and Kanya, the signs touching Karka and Simha.
All twelve lordships, rebuilt from the pattern
Run the fan to its end and the whole map falls out. Moon: Karka. Sun: Simha. Mercury: Mithuna and Kanya. Venus: Vrishabha and Tula. Mars: Mesha and Vrischika. Jupiter: Dhanu and Meena. Saturn: Makara and Kumbha — the pair opposite the royals. Nothing here needs memorizing; it needs rebuilding twice.
Forgot Scorpio's lord? Third step out from the royals: Mercury, Venus... Mars.
Rahu and Ketu own nothing
The seven bodies divide all twelve rashis with no gaps and no sharing. Rahu and Ketu — the shadow points from lesson 1.2 — hold no thrones in Parashari astrology. They express themselves through the signs and lords they attach to, a mechanic you will meet properly in the graha lessons.
If a source names Ketu 'ruler of Scorpio', that is a later convention — for Parashara, Scorpio belongs to Mars.
The one idea to keep
Every field has exactly one owner
Signs are fields; every field has exactly one owner. Whatever happens in a field is answerable to its owner — which is why every lordship rule to come starts by asking 'who owns this sign?' Know the owner on sight. The whole system stands on it.
