Yantrodharaka Hanuman Temple, Hampi, Bellary district, Karnataka India 3.54

Temple is dedicated to Lord Hanuman and the idol here is installed by Sri Vyasaraja, the Rajaguru of the Vijayanagara Kingdom.
It is believed that Sri Vyasaraja everyday used to draw a picture of Lord Hanuman on the rocks using a charcoal before he offered his prayers and the picture disappeared after the rituals were completed.
This incidence happened for 12 days in a row until Guru pleaded to the Lord to appear in front of him. On the twelfth day, Lord Hanuman appeared in front of Vyasaraja and blessed him.
It is said that the Lord himself asked Sri Vyasaraja to first constrain him in a hexagonal or a six angled amulet and install him in that place.
Lord Hanuman here is in a meditative state and when you closely look at the Lord, you would get to see the carvings of 12 monkeys holding tails of one another as they face backwards. It is a representation of the 12 days of prayers that Sri Vyasaraja did before the Lord blessed him. The crown of Lord Hanuman is his tail and there are seed syllables carved on the entire rock around the statue.
