This book addresses the thorny issue regarding the authenticity of the Yulanpen Sūtra, the scriptural source for the Yulanpen Festival or Hungry Ghost Festival in East Asia. The sūtra, which features Mulian (Skr. Maudgalyāyana) adventuring into the Preta realm to rescue his mother, is catalogued in the Chinese Buddhist bibliography with the Indo-Scythian Dharmarakṣa (Ch. Zhu Fahu, ca. 266-308) given as the translator. However, in modern Chinese, Japanese, and Western scholarship, the sūtra is more often than not regarded as a Chinese Buddhist apocryphal scripture and the Mulian myth as an apocryphal story created by Chinese Buddhists to foster the sinicisation and transformation of Indian Buddhism mainly on the grounds that there is no extant Yulanpen Sūtra in Indic sources and that the sūtra stresses Confucian filial piety and ancestor worship. This book challenges these widely held beliefs by demonstrating that filial piety and ancestor worship are not peculiar to Confucian China but also inherent in Indic traditions and that the sūtra is a Chinese creative translation rather than an indigenous Chinese composition.
