Amoghavajra was born in Samarkand of an Indian father and Sogdian mother, he went to China at age 10 after his father's death. In 719, he was ordained into the sangha by
Vajrabodhi and became his disciple.
After all foreign monks were expelled from China in 741, he and some associates went on a pilgrimage to gather texts, visiting Sri Lanka, Indochina and India. During this voyage, he apparently met Nagabodhi, Vajrabodhi's master, and studied the
Tattvasa?graha Tantra at length. He returned to China in 746 with some five hundred volumes.
In 750, he left the court to join the military governorship of General Geshu Han of the Tang dynasty, for whom he conducted large-scale tantric initiations at his field headquarters. In 754, he translated the first portion of the Tattvasa?graha Tantra texts (Taish? Tripi?aka. 865), central to the Outer Tantras of Vajrayana Buddhism, which became one of his most significant accomplishments. He regarded its teachings as the most effective method for attaining enlightenment yet devised, and incorporated its basic schema in a number of writings.
Amoghavajra was captured in the An Lushan Rebellion but in 757 was freed by loyalist forces, whereupon he performed rites to purify the capital and consolidate the security of the Tang state. Two years later, he initiated the emperor Emperor Suzong of Tang as a chakravartin.
In 765, Amoghavajra used his new rendition of the Humane King Sutra in an elaborate ritual to counter the advance of a 200,000-strong army of Tibetan and Uyghurs which was poised to invade Chang'an. Its leader, Pugu Huai'en, dropped dead in camp and his forces dispersed.
The opulent Jinge Temple on Mount Wutai was completed in 767, a pet project of Amoghavajra, one of his many efforts to promote the bodhisattva Mañju?r? as the protector of China. Amoghavajra continued to perform rites to avert disaster at the request of Emperor Daizong of Tang.
On his death in 774, three days of mourning were officially declared, and he posthumously received various exalted titles.
The Chinese monks Huilang, Huiguo and Huilin were among his most prominent successors. Seventy-seven texts were translated by Amoghavajra according to his own account, though many more, including original compositions, are ascribed to him in the Chinese canons.
The Shingon lineage is an ancient transmission of esoteric Buddhist doctrine that began in India and then spread to China and Japan. Shingon is the name of this lineage in Japan, but there are also esoteric schools in China, Korea, Taiwan and Hong Kong that consider themselves part of this lineage (as the originators of the Esoteric teachings) and universally recognize K?kai as their eighth patriarch. This is why sometimes the term "Orthodox Esoteric Buddhism" is used instead.
Shingon or Orthodox Esoteric Buddhism maintains that the expounder of the doctrine was originally the Universal Buddha Vairocana, but the first human to receive the doctrine was Nagarjuna in India. The tradition recognizes two groups of eight great patriarchs - one group of lineage holders and one group of great expounders of the doctrine.
