Lokaksema (Buddhist monk)

• 1. Introduction

  ›

  Lokaksema arrived in the Han capital Luoyang carrying something the city had never seen: Sanskrit texts from a Buddhist tradition that was still forming its identity. He was a Kushan monk, probably multilingual from birth, who flourished between 147 and 189 CE. He would become one of the first people in recorded history to translate Mahayana Buddhist texts into any language. That distinction raises a question worth sitting with. What does it mean to be first at a thing like that? Not the first to believe, not the first to preach, but the first to reach across an entirely different linguistic world and carry a tradition with you. The full answer lies in where Lokaksema came from, how he worked, and what survived.

• 2. A Man Between Worlds

  Lokaksema's Chinese name carries a small but telling clue. The prefix Zhi, which appears as the character 支, was conventionally added to the names of people of Yuezhi ethnicity. That single character places him within a broad swath of territory stretching across what is now Iran, Afghanistan, and Pakistan. He is traditionally described as a Kushan, though the Chinese term Yuezhi covered that entire region rather than a single political identity. Scholar Paul Harrison has speculated that Lokaksema's mother tongue was Bactrian, the language of the region that lay at the heart of the Kushan empire. Gandhari Prakrit, which served as the language of religion, administration, and commerce in the northwestern parts of India, was almost certainly familiar to him as well. Growing up in a crossroads culture, where trade routes met and languages overlapped, likely shaped the skills that would define his career in China. His Parthian contemporaries An Shigao and An Xuan had arrived in Luoyang slightly earlier on similar missions, illustrating that this moment of Buddhist transmission into East Asia was carried by Central Asians, not Chinese converts.

• 3. Luoyang and the Translation Years

  ›

  Toward the end of the reign of Emperor Huan of Han, whose rule ran from 147 to 168 CE, Lokaksema made his way to Luoyang. The city was the imperial capital, the eastern anchor of the Silk Roads, and a place where foreign monks could find patronage and audiences. Between 178 and 189 CE he produced a body of Chinese translations that the editors of the Taishō Tripitaka would eventually number at twelve texts. Not all of those attributions have held up to scrutiny. Scholars Erik Zurcher, Paul Harrison, and Jan Nattier examined each text in detail, and some were called into question. What Zurcher considered reasonably certain amounts to eight works, including a translation of the Astasahasrika Prajnaparamita Sutra, the Scripture on the Tusita Heaven, and the Pratyutpanna Samadhi Sutra. Harrison added one more to that confident group: the Druma-kinnara-raja-pariprccha-sutra. The collapse of the Han dynasty brought those translation years to an end. As the empire fell into chaos, Lokaksema disappeared from the historical record. No one recorded the date of his death.

• 4. Style and Tiers

  ›

  Lokaksema's approach to translation was distinctive enough that scholars have used it as a fingerprint to test which texts genuinely belong to him. He transliterated Indic terms extensively rather than finding Chinese equivalents, and he preserved the long-sentence style of Indian originals. When he encountered Indic verse, he rendered it as Chinese prose without any attempt to replicate the meter. Nattier, drawing on evidence from Chinese catalogues, proposed that the Astasahasrika Prajnaparamita Sutra and the Pratyutpanna Samadhi Sutra serve as core texts representing his style most faithfully, though both show some signs of later editing. A second tier of works, including the Scripture on the Tusita Heaven and the Mañjusri's Inquiry Concerning the Bodhisattva Career, strongly resembles those core texts while displaying occasional anomalies. A third tier, containing the Ajatasatru Kaukrtya Vinodana Sutra and the Druma-kinnara-raja-pariprccha-sutra, departs more noticeably from the distinctive pattern. Harrison raised reservations about the Aksohbhya-vyuha, and considered the Pratyutpanna Samadhi Sutra to be a product of revision rather than Lokaksema's original hand. The text known as T313, if it does originate with Lokaksema, was heavily revised by an unknown editor, though its prose sections come closer to his style than its verse.

• 5. What Was Lost

  ›

  Several texts attributed to Lokaksema did not survive at all. A version of the Suramgama-samadhi-sutra, referred to as the Shoulengyan jing, was already gone by the time the monk Sengyou compiled his records in the late fifth and early sixth centuries. Sengyou, who lived from 445 to 518 CE, is the primary biographical source for Lokaksema, and his acknowledgment that even he could not locate that text gives a sense of how quickly early translations could disappear. The Guangming sanmei jing, the Sutra on the Samadhi of Luminosity, also vanished, along with the Hu Parinirvana Sutra and the Bo benjing, the Original Pusya Sutra. Those lost works represent a gap that cannot be filled. They may have contained stylistic patterns or doctrinal emphases that would sharpen the scholarly picture of how Lokaksema worked. What remains is already enough to make his place in the transmission of Buddhism into East Asia irreplaceable, but Sengyou's testimony reminds us that the archive is incomplete.
