Xuanzang's Journey to India (629–645): The Pilgrim Monk

Xuanzang’s journey to India was a sixteen-year pilgrimage, from 629 to 645, in which a young Chinese Buddhist monk crossed the deserts and mountains of Central Asia to study at the great monastic centres of India. He returned to the Tang capital Chang’an with 657 Buddhist texts and spent the rest of his life translating them. His account of the journey remains one of the most important sources for the history of Central and South Asia in the seventh century.

Background: a monk in search of texts

Xuanzang was born around 602 in the Luoyang region of central China, into a family of officials. Following an elder brother, he became a monk as a teenager and studied in Luoyang, Chengdu and Chang’an during the violent years when the Sui dynasty collapsed and the Tang dynasty rose.

He grew dissatisfied with the Chinese translations of Buddhist scripture, which disagreed on key points of doctrine, particularly the Yogacara teaching that experience is shaped by consciousness. He resolved to go to India to study the texts in Sanskrit, as the monk Faxian had done more than two centuries earlier.

Crossing Central Asia

In 629 the new Tang government, still securing its frontiers, forbade travel to the west. Xuanzang left anyway, slipping past border posts beyond Guazhou and crossing the Gobi Desert alone, where his biography says he nearly died of thirst. He reached the oasis of Hami and then Gaochang (Turfan), whose king, Qu Wentai, tried to keep him as court teacher before agreeing to sponsor the journey with supplies, escorts and letters of introduction.

He continued through Kucha, crossed the Tian Shan mountains by a glacier pass, losing many companions to cold, and reached the camp of the Western Turkic khagan near Lake Issyk-Kul. The khagan’s protection carried him through Tashkent and Samarkand, across the Amu Darya and south to Balkh and Bamiyan, where he described the colossal standing Buddhas carved in the cliff. He then descended into Gandhara and spent about two years studying in Kashmir.

Years in India

Xuanzang travelled across northern India, visiting the places associated with the Buddha’s life, including Kapilavastu, Bodh Gaya, Sarnath and Kushinagar. He recorded that many monasteries in former Buddhist heartlands such as Gandhara were in ruins, a sign that Buddhism was declining in parts of India.

His main goal was the monastery at Nalanda in Bihar, then the greatest centre of Buddhist learning. There he studied Yogacara under the aged abbot Silabhadra, as well as Sanskrit grammar and logic. He spent roughly five years at Nalanda and in the surrounding region, then toured eastern and southern India before returning.

His learning won him fame. Around 642–643 Harsha, the ruler of much of northern India, invited him to Kanauj, where he defended Mahayana teachings at a great religious assembly. He also attended the five-yearly charity festival that Harsha held at Prayag (modern Prayagraj). King Bhaskaravarman of Kamarupa in Assam also sought his company.

The return to Chang’an

Xuanzang set out for home around 643, crossing the Hindu Kush and the Pamirs with an escort and baggage animals. Some manuscripts and seeds were lost when a boat capsized on the Indus. He stayed for several months at Khotan, sending for replacement copies, and from there wrote to Emperor Taizong admitting his illegal departure. The emperor sent a gracious reply.

He arrived in Chang’an in early 645 to large crowds, bringing 657 texts in 520 cases, relics and Buddha images. Taizong received him at Luoyang, urged him to take government office, which he declined, and asked him to write an account of the western lands. Dictated to his disciple Bianji, the Great Tang Records on the Western Regions was completed in 646.

Translator and teacher

With imperial support Xuanzang organised large translation teams, first at Hongfu Monastery and later at Da Ci’en Monastery in Chang’an. Between 645 and his death in early 664 he and his assistants translated 75 works in 1,335 scrolls, a large share of all Buddhist translations made in premodern China. He set new standards of accuracy and terminology, and his short version of the Heart Sutra, made in 649, became the standard version recited across East Asia.

To protect the texts and images he had brought, the Giant Wild Goose Pagoda was built at Da Ci’en Monastery in 652. His disciple Kuiji developed his teachings into the Faxiang school of Chinese Buddhism, which was carried to Japan and Korea.

Key people

Xuanzang himself is the central figure: a gifted scholar who combined physical endurance with diplomatic skill, winning the support of kings who were not Buddhists as well as those who were. He is also known in older Western books as Hiuen Tsang or Hsüan-tsang.

Qu Wentai, king of Gaochang, made the journey possible by providing money, about two dozen servants, horses, robes and letters to some two dozen rulers along the route. His kingdom was conquered by the Tang in 640, and he died during the invasion, so Xuanzang could not visit him on the way home as he had promised.

Silabhadra, the elderly abbot of Nalanda, was regarded as the leading Yogacara master of his day and taught Xuanzang the treatise that had drawn him to India. Harsha (reigned c. 606–647), ruler of Kanauj and most of northern India, became his patron and honoured him at public assemblies.

Emperor Taizong first forbade the journey and then embraced its results. He supported the translation work, wrote a preface to Xuanzang’s translations, and valued the Great Tang Records as intelligence on lands where Tang power was expanding.

By the numbers

Legacy

The Great Tang Records describes cities, climate, languages, customs, rulers and monasteries with unusual precision. In the nineteenth century, British archaeologists such as Alexander Cunningham used it as a guide to identify Buddhist sites in India, including Nalanda. His biography, written by the monks Huili and Yancong, adds vivid detail about his life.

His journey also became legend. Storytellers expanded it over centuries, and the sixteenth-century novel Journey to the West made him the pious monk Tang Sanzang, escorted by the Monkey King, one of the best-known characters in East Asian literature. Statues and memorial halls in Xi’an and at Nalanda honour him today.

Why it matters

Xuanzang’s pilgrimage transformed Chinese Buddhism through the texts he translated, and his careful record preserved knowledge of Central Asian and Indian societies that would otherwise be lost. It is one of the great journeys of the medieval world and a lasting symbol of cultural exchange along the Silk Road.
