LAWS
The laws of astrology are the foundations and rules that are essential to know before doing readings. These laws help us to understand the signs, planets, houses and the relationship between them all.
Modality & Elements
Zodiac signs can be categorized in a manner which makes each of them unique. As there are 12 zodiac signs, they all belong to one of the 3 modalities and one of the 4 elements, which are as follows:

Fun facts:
-
The luminaries (sun & moon) rule one sign each.

Each of the planets & lumaries (counted as one) creates a pattern in the zodiac wheel chart, as seen on the following image.

Planets in houses and signs
Houses: Joys & co-signs
A planet’s joy is the house where it shines at its absolute best. A co‑sign is where it feels at home. But if you’re choosing between the two, joys carry the greater power; they reveal a planet’s highest expression.
Signs: Exaltation & domicile
Similarly to joys and co-signs, a planet does the best of best in its sign of exaltation, while it feels at home in the signs of its domicile, because like its name, it feels most at home there. It's also domiciled in the very same signs it rules.
Planet | Joy | Co-Sign | Exaltation | Domicile |
|---|---|---|---|---|
9 | 4, 11 | Aries | Leo | |
3 | 7 | Taurus | Cancer | |
1 | 6 | Virgo | Gemini, Virgo | |
5 | 5, 12 | Pisces | Taurus, Libra | |
6 | 3, 10 | Capricorn | Aries, Scorpio | |
11 | 2, 9 | Cancer | Sagittarius, Pisces | |
12 | 1, 8 | Libra | Capricorn, Aquarius |
The opposite also applies;
When a planet is in the opposite house of its joy or co-sign, it's considered on the opposite side of the spectrum. So just as good it is in joy, the worse it is in the opposite house of joy.
The same applies for exaltation and domicile. When the planet is in the opposite sign of its exaltation, it's called the planet being in 'fall', and when in the opposite sign of its domicile, it's called 'detriment'.
*As for the opposite houses of joys and co-signs, there are no common words used to describe them.
