Kumārajīva in the context of "Aksu City"

The Amitābha Sūtra (Ch.: 阿彌陀經, pinyin: Āmítuó Jīng, or 佛說阿彌陀經, Fóshuō Āmítuó Jīng; Jp.: Amida Kyō, Vi.: A Di Đà Kinh), also known as the [Shorter] Sukhāvatīvyūha Sūtra (Sanskrit, The Array of "the Blissful Land", or The Arrangement of Sukhāvatī) is one of the two Indian Mahayana sutras that describe Sukhāvatī, the pure land of Amitābha. The text was translated into Chinese in 402 by Kumārajīva (Taishō Tripiṭaka no. 366) and it is also known in Chinese as the "Small Sutra" (Xiaojing).

The Amitābha Sūtra is highly influential in East Asian Buddhism, including China, Korea, Japan, and Vietnam since it is considered one of the "Three Pure Land" sutras which are the key scriptures in Pure Land Buddhism.

Qin, known in historiography as the Later Qin (simplified Chinese: 后秦; traditional Chinese: 後秦; pinyin: Hòuqín; 384–417) or Yao Qin (姚秦), was a dynastic state of China ruled by the Yao clan of Qiang ethnicity during the Sixteen Kingdoms period in northern China. As the only Qiang-led state among the Sixteen Kingdoms, it was most known for its propagation of Buddhism under its second ruler, Yao Xing, who sponsored the Madhyamakin monk, Kumārajīva to translate Sanskrit Buddhist text into Chinese.

All rulers of the Later Qin declared themselves emperors, but for a substantial part of Yao Xing's reign, he used the title Heavenly King. Historiographers gave the state the prefix of "Later" to distinguish it with the Former Qin and Western Qin as it was founded during the Former Qin's collapse after the Battle of Fei River and went on to conquer the Former Qin's power base in the Guanzhong. With Chang'an as its capital, the Later Qin also controlled Henan and vassalised the Western Qin, the four Liangs (Later, Southern, Northern and Western), Southern Yan, Qiao Shu, Chouchi and various tribes of the Ordos region.

Āryadeva (fl. 3rd century CE) (IAST: Āryadeva; Tibetan: འཕགས་པ་ལྷ་, Wylie: 'phags pa lha, Chinese: 提婆 菩薩 Tipo pusa meaning Deva Bodhisattva), was a Mahayana Buddhist monk, a disciple of Nagarjuna and a Madhyamaka philosopher. Most sources agree that he was from "Siṃhala", which some scholars identify with Sri Lanka. After Nagarjuna, he is considered to be the next most important figure of the Indian Madhyamaka school.

Āryadeva's writings are important sources of Madhyamaka in East Asian Buddhism. His Catuḥśataka (Four Hundred Verses) was influential on Madhyamaka in India and China and his *Śataka (Bailun, 百論, T. 1569) and Dvādaśamukhaśāstra (both translated by Kumārajīva in the 4th century) were important sources for the East Asian Madhyamaka school. Āryadeva is also known as Kanadeva, recognized as the 15th patriarch in Chan/Zen Buddhism and some Sinhalese sources also mention an elder (thera) called Deva which may also be the same person. He is known for his association with the Nalanda monastery in modern-day Bihar, India.
