Lokakṣema (लोकक्षेम, Chinese: 支婁迦讖; pinyin: Zhī Lóujiāchèn) (flourished 147–189) was a Kushan Buddhist monk who travelled to China during the Han dynasty and is one of the first known translators of Mahayana religious texts into any language.
[1] Details of Lokakṣema's life come to us via a short biography by Sengyou (僧祐; pinyin: Sēngyòu; 445–518 CE) and his text "Collected Records concerning the Tripitaka" (出三藏記集 Chu sanzang jìjí, T2145).
[3] Lokaksema's translation activities, as well as those of the Parthians An Shigao and An Xuan slightly earlier, or his fellow Yuezhi Dharmarakṣa (around 286 CE) illustrate the key role Central Asians had in propagating Buddhism to the countries of East Asia.
With the decline and fall of the Han, the empire fell into chaos and Lokakṣema disappears from the historical record so that we do not know the date of his death.
If T313 was indeed a translation by Lokakṣema, it has been extensively revised by an unknown editor, though the prose sections are closer to his style than the verse.
