Vajrabodhi (वज्रबोधि, , 671–741) was an Indian esoteric Buddhist monk and teacher in Tang China. He is one of the eight patriarchs in Shingon Buddhism. He is notable for introducing Vajrayana Buddhism in the territories of the Srivijaya Empire which subsequently evolved into a distinct form known as Indonesian Esoteric Buddhism. Vajrabodhi was the second of three Vajrayana missionaries to eighth-century China. He was born of a Tamil Vellalar family, and his father was a priest for the royal house. Vajrabodhi probably converted from Saivism family to Buddhism at the age of sixteen, although some accounts place him at the Buddhist institution of Nālandā at the age of ten. He studied all varieties of Buddhism and was said to have studied for a time under the famous Buddhist logician Dharmakīrti. Under Santijnana, Vajrabodhi studied Vajrayāna teachings and was duly initiated into yoga. Leaving Agastya Mala of the Pothigai mountain range of India, Vajrabodhi traveled to Sri Lanka and Sriwijaya (present-day Palembang in the south of Sumatra Island, Indonesia), where he apparently was taught a Vajrayāna tradition distinct from that taught at Nālandā. This Tamraparniyan route had been traversed by several scholars prior, and mirrored the reach of Agastya. From Srivijaya he sailed to China via the escort of thirty-five Persian merchant-vessels, and by AD 720 was ensconced in the Jianfu Temple at the Chinese capital, Chang'an (present-day Xian). Accompanying him was his soon-to-be-famous disciple, Amoghavajra. Like Subhakarasimha, who preceded him by four years, Vajrabodhi spent most of his time in ritual activity, in translating texts from Sanskrit to Chinese, and in the production of Esoteric art. Particularly important was his partial translation of the Sarvatathāgatatattvasagraha between the years 723 and 724. This Yoga Tantra - along with the Mahāvairocana Sutra, translated by Subhakarasimha the same year - provides the foundation of the Zhenyan school in China and the Shingon and Esoteric branch of the Tendai school in Japan.
