全胜（梵文：संजय）在摩诃婆罗多中是持国的重臣，负责为国王汇报。俱卢大战前夕，持国希望得到毗耶娑的协助，但又不想自己目睹骨肉相残的战况，结果毗耶娑赐予全胜成为开天眼的全知者，让全胜可以向瞎眼的持国汇报俱卢大战的战况。

Sanjaya (Sanskrit: संजय, meaning "victory") or Sanjaya Gavalgani is a character from the ancient Indian historic battle Mahābhārata. In Mahabharata—an epic poem of war between the Pandavas and the Kauravas—the blind king Dhritarashtra is the father of the principals of the Kaurava side. Sanjaya, son of charioteer Gavalgana, is Dhritarashtra's advisor and also his charioteer.Sanjaya was a disciple of sage Krishna Dwaipayana Veda Vyasa and was immensely devoted to his master, King Dhritarashtra. Sanjaya—who has the gift of seeing events at a distance almost 80 KM of the length(divya-drishti) right in front of him, granted by the sage Vyasa—narrates to Dhritarshtra the action in the climactic battle of Kurukshetra, which includes the Bhagavad Gita. Before this great war broke out, Sanjaya had gone to Yudhishtira as the Ambassador of Kauravas to negotiate on behalf of them.
