Buddhism, primarily the Sarvastivada, but eventually also Mahayana Buddhism during the Uighur period. In this respect it differed from Khotan, a Mahayana-dominated kingdom on the southern side of the desert. According to the Book of Jin, during the third century there were nearly one thousand Buddhist stupas and temples in Kucha. At this time, Kuchanese monks began to travel to China. The fourth century saw yet further growth for Buddhism within the kingdom. The palace was said to resemble a Buddhist monastery, displaying carved stone Buddhas, and monasteries around the city were numerous. Kucha is well known as the home of the great fifth-century translator monk Kumārajīva (344-413). Monks Po-Yen A monk from the royal family known as Po-Yen travelled to the Chinese capital, Luoyang, from 256-260. He translated six Buddhist texts into Chinese in 258 at China's famous White Horse Temple, including the Infinite Life Sutra, an important sutra in Pure Land Buddhism. Po-Śrīmitra Po-Śrīmitra was another Kuchean monk who traveled to China from 307-312 and translated three Buddhist texts. Po-Yen A second Kuchean Buddhist monk known as Po-Yen also went to Liangzhou (modern Wuwei, Gansu, China) and is said to have been well respected, although he is not known to have translated any texts. Tocharian languages The language of Kucha, as evidenced by surviving manuscripts and inscriptions, was Kuśiññe (Kushine) also known as Tocharian B or West Tocharian, an Indo-European language. Later, under the Uighur domination, the Kingdom of Kucha gradually became Turkic speaking. Kuśiññe was completely forgotten until the early 20th century, when inscriptions and documents in two related (but mutually unintelligible) languages were discovered at various sites in the Tarim Basin. Conversely, Tocharian A, or Ārśi was native to the region of Turpan (known later as Turfan) and Agni (Qarašähär; Karashar), although the Kuśiññe language also seems to have been spoken there. While written in a Central Asian Brahmi script used typically for Indo-Iranian languages, the Tocharian languages (as they became known by modern scholars) belong to the centum group of Indo-European languages, which are otherwise native to southern and western Europe. The precise dating of known Tocharian texts is contested, but they were written around the 6th to 8th centuries CE (although Tocharian speakers must have arrived in the region much earlier). Both languages became extinct before circa 1000 CE. Scholars are still trying to piece together a fuller picture of these languages, their origins,
