Note 3 — Chapter XXIX · GṚIDHRA-KÛṬA HILL, AND LEGENDS. FÂ-HIEN PASSES A NIGHT ON IT. HIS REFLECTIONS.
James Legge translation
See M. B., p. 320. Hardy says that Devadatta’s attempt was ‘by the help of a machine;’ but the oldest account in the Sacred Books of the East, vol. xx, Vinaya Texts, p. 245, agrees with what Fâ-hien implies that he threw the rock with his own arm.
