The 8th sign is Vrischika (Scorpio). Parashara describes Vrischika as follows:

“It has a slender physique and is a centipede rashi. It denotes Brahmins and resides in holes. Its direction is north and is strong during daytime. It is reddish brown and relates to water and land. It has a hairy physique and is very sharp (or passionate). Mangal is its ruler.”

Mangal (Mars) is the ruler and Vrischika is a fixed, watery and female sign. The Mangal that made Mesha (Aries) so enterprising and energetic, plays a much more defensive and protective role here. It is defending its delicate watery/female core.

The symbol choosen for Vrischika sign is the Scorpion, an animal that is known for its ability to defend itself.

People with a prominent Scorpio can be very warm and sweet, if left unchallenged and unthreatened. They rather not change their position, but defend themselves if someone tries to harm them. Their tendency to be fixed can make them appear to be controlling, but their true nature is to nurture. Just don’t tease them.
