Hui-neng ［慧能］ (638–713) (PY Huineng; Enō): The sixth patriarch of the Zen (Ch’an) school in China. He was also known as the Great Teacher Ts’ao-ch’i because he lived at Pao-lin-ssu temple in Ts’ao-ch’i. According to Zen tradition, he became a disciple of Hung-jen, the fifth patriarch of Chinese Zen. Hung-jen eventually chose Hui-neng as his successor over his most senior disciple, Shen-hsiu. Hui-neng then moved south to Pao-lin-ssu where he devoted himself to training disciples. After Hung-jen’s death in 674, the Zen school split into two—the Northern school, headed by Shen-hsiu, and the Southern school, headed by Hui-neng. The Southern school quickly became the predominant school of Zen. Hui-neng’s words are preserved in a work called The Platform Sutra of the Sixth Patriarch.
