Kumarajiva

Kumarajiva (鸠摩罗什; also written Kumārajīva, 略称罗什, meaning in Chinese rendering 童寿) was a Buddhist monk and translator of Indian descent, brought to China by force of arms, who became state preceptor to the Later Qin ruler 姚兴 and directed the Later Qin court's official scriptural translation bureau.^{1 • 2} The standard history 《晋书》 records his life in chapter 95, and names him again in chapter 122.^{1 • 3}

Origins and family

The 《晋书》 states that Kumarajiva's family came from 天竺 and had served as state ministers for generations. His father 鸠摩罗炎, described as intelligent and a man of great integrity, was due to inherit the chancellorship but withdrew and became a monk, crossing east over the 葱岭. The king of 龟兹, hearing his name, met him outside the city walls and made him state preceptor; the king then pressed his twenty-year-old sister, talented and quick-witted, on 炎 as a wife. While Kumarajiva was in the womb his mother showed unusual understanding, and when the boy was seven the mother left home with him to become a nun.¹

As a boy he studied under a master, reciting a thousand gathas a day, each gatha of thirty-two characters, thirty-two thousand characters in all, and grasping their meaning unaided. At twelve his mother took him to 沙勒, whose king honored him greatly and where he stayed a year, exhausting the five fields of learning and the studies of yin-yang, stars and calculation, and reading omens so accurately that his words matched the tally. By temperament he was open and unrestrained, indifferent to minor discipline, which made other practitioners suspect him; he paid no heed, devoted himself to teaching the Mahayana, and the students all took him as master. At twenty the king of 龟兹 welcomed him back, where he expounded the sutras widely and no visiting scholar could match him.¹

His mother then left 龟兹 for 天竺, telling him that the profound teaching should be transmitted to the eastern lands through him, though at no benefit to himself. He answered that if the great teaching could flow abroad, hardship would leave him without regret. In the western regions the kings so revered him that at his lectures they knelt at the side and let him step on their bodies to ascend the seat.¹

Career

The Former Qin ruler 苻坚 heard of him and secretly wished to bring him east; when the court astrologer reported a star in the field of a foreign land presaging a great wisdom coming to aid China, 苻坚 sent the general 吕光 with seventy thousand troops west against 龟兹, instructing that if Kumarajiva were captured he be rushed by post-horse.¹ The expedition against 龟兹 was sent out in 382 (前秦建元十八年).⁵ Before the army arrived, Kumarajiva warned the 龟兹 king 白纯 that his state's fortune was failing and a strong enemy was coming from the sun's setting, and that he should submit rather than resist. 白纯 ignored him and fought; 吕光 defeated him and captured Kumarajiva.¹

吕光 treated the captive as spoils: seeing him young, he forced him to marry the 龟兹 king's daughter, and when Kumarajiva refused bitterly, made him drink wine and shut them in a sealed room until he yielded.¹ On the return march 吕光 camped at the foot of a mountain against Kumarajiva's advice to move to the high ground of 陇上; that night heavy rain raised a flood several zhang deep that killed several thousand men.¹ Reaching 凉州, 吕光 learned that 苻坚 had been killed by 姚苌 and proclaimed himself ruler in the 河右.¹ Kumarajiva remained in 凉州 for years, since 吕光 and his successors did not promote the dharma, and he kept his deep understanding unexpressed.¹

In 凉州 he acted as an omen-reader and adviser. When a great wind struck 姑臧 he predicted a rebellion that would collapse on its own, which occurred. Asked by 吕光 to assess a campaign against 段业, whom opinion expected 吕纂 to crush, he answered that he saw no advantage in the expedition; 吕纂 was then beaten at 合黎 and again by the rebel 郭黁, escaping with his life alone.¹

The Later Qin ruler 姚兴 sent 姚硕德 west; 吕隆 was defeated and Kumarajiva was welcomed to 长安, treated with the rites of state preceptor and installed in the 西明阁 and the 逍遥园 to translate.¹ Finding the old translations full of errors, and drawing on his memory of the texts, he directed a bureau in which 姚兴 had the monks 僧睿, 僧肇, and more than eight hundred others transmit his interpretations, producing over three hundred juan of sutras and treatises. He loved the Mahayana and wished to expound it, lamenting that too few understood it deeply to justify his composing a Mahayana Abhidharma; the only work he wrote was the two-juan 《实相论》 for 姚兴, who revered him like a god.¹ 姚兴's reign (394–416) is regarded as a climax of imperial sponsorship of Buddhism in northern China, with the ruler personally involved in the translation enterprise.⁶

Military role

His military significance lay in counsel to 吕光. He predicted the 龟兹 defeat before it came, urged moving the army to 陇上 high ground before the flood that killed thousands, judged the campaign against 段业 as disadvantageous before 吕纂's two defeats, and read the portents at 姑臧 and under 吕纂's reign as warnings of rebellion and regicide, each borne out by events the history then records.¹

Death, titles, and heirs

Kumarajiva died in 长安. 姚兴 had the body cremated at the 逍遥园 according to a foreign rite; when the firewood was consumed the form was destroyed, only the tongue did not burn.¹

The death year is disputed: the 高僧传 gives 弘始十一年 (409), while Sengzhao's eulogy gives the guichou year, 弘始十五年 (413); the 佛光大辞典 records 344–413 with an alternative 350–409.^{4 • 2} 姚兴 had forced ten courtesans on him, saying a master of such insight should not leave the seed of dharma without heir, after which he no longer dwelt in the monks' quarters; the history records two sons born of a palace woman.¹

Assessment

The 《晋书》 biography is built around fulfilled predictions and includes the episodes of forced marriage and the ten courtesans.¹ On translation, 梁启超 called him a first-rate master of the translator's art, and modern comparison holds that while Xuanzang translated far more in volume, Kumarajiva ranks higher for the content and enduring influence of what he chose to translate.^{7 • 8}

Legacy

Many of his translations remain in liturgical use, still read in his versions with little change.⁷ A memorial survives at 草堂寺: the Eight-Treasure Jade Stupa, 246 cm tall, eight-sided and twelve-tiered.⁹ A Dunhuang manuscript, S.381, preserves a short independent biography that differs from the traditional sources and offers a new record for studying his life.¹⁰
