Yantroddhara Hanuman in Hampi, Karnataka, India. Inspired by a dream Sri Vyaasaraya drew the image of Hanumaan on a stone several times. Each time the picture took the form of a monkey and leapt away. Sri Vyaasaraya slept that day seeking Sri Hanumaan to solve the problem. He was directed in a dream to encircle the picture with a yantra (consecrated geometrical shapes with beeja aksharas - primordial letters like OM). Next day, Sri Vyaasaraya drew the above picture as ordained and is called as Sri Yantroddhara Hanumaan
