Gulika, which is also known as Mandi is the son of Planet Saturn. Though it is a sub-planet it has great influence in a horoscope. Gulika is said to be SARVA HANTHARE (destroyer of all).
Generally speaking only astrologers from Kerala (southern state of India) calculate the position of Gulika in a Horoscope. Some say it is due to that reason predictions of Kerala astrologers are more accurate. People from other states visit Kerala only to get astrological consultation.
Gulika is the most malefic among the sub-planet, especially when it is associated with Saturn. If Gulika is combined with a benefic planet, that planet will lose its good qualities and if Gulika is combined with a malefic planet, that planet's bad qualities will increase two fold. It will also affect the house in which it occupies and the lord of the house also. But however if it occupies 11th house, it is said to produce good results.
Birth of Gulika
During Tretha Yuga when lanka was ruled by Ravan, he ordered all the planets to sit in the 11th house (the most auspicious house) of his son - Indrajith when he was about to be born. Fearing Ravan all the planet sat in the 11th house but Shani moved to 12th house (the most inauspicious house) just before he was born and Indrajith had all the other planets in 11th house except Shani in 12th house. Ravan outraged by this cut Shani's feet and Gulika is said to be the broken feet of Shani.
