Twentieth century scholarship revealed that the story of Huineng's Buddhist career was likely invented by the monk Heze Shenhui, who claimed to be one of Huineng's disciples and was highly critical of Shenxiu's teaching.
Huineng is regarded as the founder of the "Sudden Enlightenment" Southern Chan school of Buddhism, which focuses on an immediate and direct attainment of Buddhist enlightenment. The Platform Sutra of the Sixth Patriarch (六祖壇經), which is said to be a record of his teachings, is a highly influential text in the East Asian Buddhist tradition. (Source Accessed July 14, 2021)

It is often linked with The Heart Sutra and The Diamond Sutra to form a trio of texts that have been revered and studied for centuries. However, unlike the other sutras, which transcribe the teachings of the Buddha himself, The Platform Sutra presents the autobiography of Hui–neng, the controversial 6th Patriarch of Zen, and his understanding of the fundamentals of a spiritual and practical life. Hui–neng's instruction still matters—the 7th–century school of Sudden Awakening that he founded survives today, continuing to influence the Rinzai and Soto schools of contemporary Zen.
Red Pine, whose translations of The Heart Sutra and The Diamond Sutra have been celebrated and widely received, now provides a sensitive and assured treatment of the third and final sutra of the classic triumvirate. He adds remarkable commentary to a translation that, combined with the full Chinese text, a glossary, and notes, results in a Mahayana masterpiece sure to become the standard edition for students and seekers alike.

The Platform Sutra of the Sixth Patriarch consists of a record of the teachings of Hui-neng, the Sixth Patriarch of the Chan School in China, recorded by his disciple Fahai, and is known by several abbreviated titles such as Platform Sūtra or Platform Sūtra of the Dharma Treasure. It proclaims the independence of the Southern School of Chan from the Northern School on such subjects as "sudden enlightenment" (Ch. dun-wu) and the external expression of one's real nature (Ch. jian-xing).

Phillip B. Yampolsky has based his translation on the Tun-huang manuscript, the earliest extant version of the work. A critical edition of the Chinese text is given at the end of the volume.
Dr. Yampolsky also furnishes a lengthy and detailed historical introduction which contains much information hitherto unavailable even to scholars, and provides the context essential to an understanding of Hui-neng's work. He gives an account of the history and legends of Ch'an Buddhism, with particular attention to the traditions associated with Hui-neng, quoting or summarizing the most important narratives. He then discusses the various texts of the Platform Sutra, and analyzes its contents. (Source: Columbia University Press)
