Wikipedia Overview

Mulian Rescues His Mother or Mulian Saves His Mother From Hell is a popular Chinese Buddhist tale first attested in a Dunhuang manuscript dating to the early 9th century CE. It is an elaboration of the canonical Yulanpen Sutra which was translated from Indic sources by Dharmarakṣa sometime between 265 and 311 CE. Maudgalyayana, whose abbreviated Chinese transliteration is Mulian, seeks the help of the Buddha to rescue his mother, who has been reborn in the preta world or in the Avici Hell, the karmic retribution for her transgressions. Mulian cannot rescue her by his individual effort, however, but is instructed by the Buddha to offer food and gifts to monks and monasteries on the fifteenth day of the seventh lunar month, which established the Ghost Festival. While Mulian's devotion to his mother reassured East Asians that Buddhism did not undermine the Confucian value of filial piety and helped to make Buddhism into a Chinese religion, it also reflected strong undercurrents of filial piety that existed throughout Indian Buddhism as evidenced through its canonical texts and epigraphical remains.
