Abhayakaragupta

Abhayākaragupta (Wylie: 'jigs-med 'byung-gnas sbas-pa) was a Buddhist monk, scholar and tantric master (vajracarya) and the abbot of Vikramasila monastery in modern-day, Bihar in India. He was born in somewhere in Eastern India, and is thought to have flourished in the late 11th-early 12th century CE, and died in 1125 CE.

Abhayākaragupta's magnum opus, the Vajravali, is a "grand synthesis of tantric liturgy" which developed a single harmonized tantric ritual system which could be applied to all Tantric Buddhist mandalas. According to A.K. Warder, Abhayākaragupta developed the Mantrayana-Madhyamaka doctrine to its final Indic form. Matthew Kapstein sees him as "among the last great masters of Buddhism in India."
