The Diamond Sutra
The Diamond Sutra, "The Perfection of Wisdom Sutra that Cuts like a Thunderbolt," is a short Mahayana sutra of the Perfection of Wisdom genre, which teaches the practice of the avoidance of abiding in extremes of mental attachment. A copy of the Diamond Sutra, found sealed in a cave in China in the early 20th century, is the oldest known dated printed book, with a printed date of 868 CE.
Since it can be read in approximately forty minutes, the Diamond Sutra is often memorized and chanted in Buddhist monasteries. This sutra has retained a high degree of popularity in the Mahayana Buddhist tradition for over a millennium, especially in East Asia, and most importantly within the East Asian meditation (Chan/Seon/Zen/Thien) school, where it is recited, taught, and commented extensively, even today. The text resonates with a core aspect of Chan doctrine/praxis: the theme of "non-abiding."
