Note 1 — THE DIAMOND SUTRA
William Gemmell translation
It is generally supposed that the familiar introductory phrase, “Thus have I heard,” was adopted by the writers or editors of Buddhist Sutras in order that their scriptures might assume the same high degree of authority as the Brahmanas and the Mantras, “as forming the ‘S’ruti’ or sacred revelation of the followers of the Vedas.” (Compare Max Müller’s History of Sanscrit Literature and the valuable note in Beal’s Kin-Kong-King)
