The twelve jyotirlinga’s are Somnath, Mallikarjuna, Mahakaleswar, Omkareshwar, Kedarnath, Bhimashankar, Viswanath, Triambakeshwar, Vaidyanath, Nageswar, Rameshwar and Grishneshwar.
Each of the 12 Jyotirlinga, is mapped to one raasi (zodiac sign) and maharshis have advocated that every person has a personal jyotirlinga. A personal Jyotirlinga is directly connected to his Atma like an Ishta devata and worshipping it can help a person come out from his past birth sins. One can work towards purifying himself and clearing the obstacles and blocks that come in way of success in every area of work and lead a happy life by worshipping his zodiac jyotirlinga.
