This is considered as the most feared sign among all the zodiac signs in Vedic Astrology as well as in Western and other forms of Astrology. And this fear starts taking its roots right from the symbol of this sign which is a Scorpio and which is full of poison. In Vedic Astrology, Scorpio is considered as the eighth zodiac sign among the twelve zodiac signs which are taken into consideration for making astrological calculations based on Vedic Astrology. The fourth pada of the Nakshatra Vishakha and all four padas of the Nakshatras Anuradha and Jyeshtha are ruled by this sign called Scorpio. And as this sign rules the fourth pada of Jyeshtha Nakshatra, it becomes important to study in a horoscope as the placement of the Moon in the fourth pada of Jyeshtha Nakshatra leads to the formation of the defect called Gandmool Dosh.
Scorpio is a watery sign and it is ruled by Mars. The Moon which is considered to be associated with care and tenderness, get debilitated in this sign which means that out of all the twelve zodiac signs, the Moon is considered as the weakest when placed in this sign. This sign can do mild to serious damages to the significances of the Moon when placed in it as the Moon also undergoes the defect named Gandmool Dosh when placed in the last parts of this sign. The weakness of the Moon combined with the Gandmool Dosh can seriously disturb the significances of the Moon which directly rules the emotions and peace of mind of the human beings. So the placement of the Moon in this sign in a horoscope can have mild to serious negative effects on the peace of mind of the native depending upon the other factors of his horoscope.
And the negativity of this sign is not limited to the Moon but it extends to many more planets and in fact most of the planets experience one or the other negative effect on their significances when placed in this sign. The planets like the Sun, Mercury, Jupiter and Venus, they all show one or more negative traits when they are placed in Scorpio in a horoscope and accordingly the native may suffer from mild to serious negative effects by virtue of placement of some specific planet or planets in this sign.
Scorpio represents the excretory organs like Anus, Rectum and some other organs in the same region in human body. Strong afflictions to this sign from one or more than one negative planets in a horoscope by virtue of their placement or aspect can make the native suffer from diseases related to the organs ruled by this sign. Such native may suffer from Piles, Fissures and other diseases in the same region.
