Baba Baidyanath dham is one of the twelve Jyotirlingas, the most sacred abodes of Shiva. It is located in Deoghar in the Santhal Parganas division of the state of Jharkhand, India. It is a temple complex consisting of the main temple of Baba Baidyanath, where the Jyotirlinga is installed, and 21 other temples.
Originally there were believed to be 64 jyothirlingas while 12 of them are considered to be very auspicious and holy, Baba Baidyanath being one of the 12 holy Jyotirlinga. The primary image is lingam representing the beginningless and endless Stambha pillar, symbolizing the infinite nature of Shiva.
According to Hindu beliefs, the demon king Ravana worshipped Shiva at the current site of the temple to get the boons that he later used to wreak havoc in the world. Ravana offered his ten heads one after another to Shiva as a sacrifice. Pleased with this, Shiva descended to cure Ravana who was injured. As he acted as a doctor, he is referred to as Vaidhya ("doctor"). From this aspect of Shiva, the temple derives its name.
Millions of pilgrims visit this shrine every year. It is famous for the mela of Shraavana (a month of the Hindu calendar), between July and August. About 8 to 10 million devotees visit the place from various parts of India and offer holy water of Ganges to the deity collected from Sultanganj, which is almost 108 km from Deoghar and Baidyanath. The water is also brought by the Kānvarias, who carry the water in Kavadi, and walk all the distance, on barefoot.
The Maa Parvathi temple is tied up with the main temple, with huge red sacred threads which is unique and worthy of reverence, showing the unity of Shiva and Shakti. According to the stories narrated in the Shiva Purana, the holy Baidyanath temple resembles the unity of souls and thus fits marriage for Hindus.
