The Diamond Sutra is a Buddhist wisdom text. Written in the form of a dialogue between the Buddha Gautama and a questioning disciple, it emphasizes the fleeting nature of the material world and posits that enlightenment cannot be achieved through rational thought. A wood block-printed copy of the sutra held at the British Library is the earliest known printed text with a date—868 CE—predating the Gutenberg Bible by about 587 years. The copy, in scroll form, is roughly how many feet long? Discuss
