Abhayadatta Sri (also known as AbhayadattaśrīorAbhayadāna) was a 12th-century Indian Buddhist monk notable for composing the Caturaśītisiddhapravrtti (the lives of the eighty-four mahasiddhas) which detailed the backgrounds of the mahasiddhas who were tantric masters. His work was later translated into Tibetan.[1][2] His story on the lives of the mahasiddhas was influential in showing their highly unconventional paths to achieving realization.[2]
He was a native of Campara which has been identified with modern day Champaran districtinBihar, India.[3] He was also a disciple of Vajrasana who was one of the last great siddhas of the eleventh century.[4]
