Note 2 — Chapter XXXVI · IN PATNA. FÂ-HIEN’S LABOURS IN TRANSCRIPTION OF MANUSCRIPTS, AND INDIAN STUDIES FOR THREE YEARS.
James Legge translation
(2) Mahasanghikah simply means “the Great Assembly,” that is, of monks. When was this first assembly in the time of Sâkyamuni held? It does not appear that the rules observed at it were written down at the time. The document found by Fâ-Hien would be a record of those rules; or rather a copy of that record. We must suppose that the original record had disappeared from the Jetavana vihâra, or Fâ-Hien would probably have spoken of it when he was there, and copied it, if he had been allowed to do so.
