Baidyanath Dham also known as Baba Baidyanath Dham. It is about 12 jyotirlingas in our India and Baidyanath is one them. Ravana has sacrificed his ten heads to Lord Shiva as a sacrifice. Pleased with this, Lord Shiva has come down to cure Ravana because he was injured. Shiva acted as a doctor, so he has been called vaidhya (“doctor”). From this aspect of Shiva, this temple got its name as Baidyanath Dham.
