Gurgaon is the most rapidly developing colonnade of the state, located in the National Capital Region. It has become one of the most important corporate and industrial hubs of India. In Mahabharat times, Gurgaon was a thick forest where the ashram of Guru Dronacharya existed. It was here that Pandav and Kourav princes got their training in arms and warfare. Because of Guru Dronacharya's ashram, people started calling it the 'Gurugram' which later on changed into 'Gurgaon'. This place had been gifted by Yudhister to Guru Dronacharya, as 'guru-dakshina'.
