The Book "Jaina and Buddhist" Religions in Haryana: A Study (6th c B.C. to 1200 A.D.) is a remarkable study about Jainism and Buddhism in Haryana. It is based on my personal exploration and village-to-village survey. I participate many excavation sites of Haryana and in-situ field study. It is my original and first hand research work on above said subject. The Land of Kurus (Haryana) had also the privilege of being the home of Indian spiritual thoughts. Tradition has it that the region was blessed by the teachings of Buddha, Mahavira, Guru Nanak and many others. Haryana is the region where eight fold ethical conduct (i.e. tapes, Satya, Ksama, Daya, Dana, Yoge, Purity) was cultivated. Both the Master, Mahavira and Buddha visited Haryana with a view to guide the people of this country. Once upon a time, this region was fed by the Sarasvati and the Darshavati, which now-a-days are seasonal rivulets and have disappeared completely. In the sixth cen. B.C. Haryana was a part of kuru- mahajan pada. During this period Mahavira and Buddha visited Kuru Mahajanpada and teaching delivered to the people of this region.
