This work examines the fascinating tale of Biluhar and Yuzasif, a story that has traveled through various cultures and religious traditions, particularly Buddhism, Christianity, and Islam. The story centers around Yuzasif, believed by many scholars to represent the historical figure of Buddha, and his spiritual mentor, Biluhar. Their conversations and exchanges explore deep philosophical and religious themes, including the nature of suffering, the path to enlightenment, and the soul’s relationship with the divine. This allegory became prominent in Islamic literature, shedding light on how early Islamic scholars viewed and interacted with the religious ideas of Buddhism and other faiths. This text is also a key part of comparative religion studies, revealing the intersections of spiritual thought across different traditions.
