Synopsis Visuddhimagga or "The Path to Complete Purification" is a great work, " a mine of historic interest" in the words of Mrs Rhys-Davids, by the well-known fourth century stalwart Buddhaghosa who has in this work faithfully preserved ancient Buddhist traditions and who "enjoys a well-merited reputation among the Buddhist of Ceylon, Burma and Saim". The present edition of the Visuddhimagga is based chiefly on four manuscripts belonging respectively to the library of King Thebaut of Burma, Henry Rigg, Prof. T.W. Rhys-Davids and Reverend Dr. Richard Morris. It is almost wholly the work of Henry Clarke Warren with a small exception, viz. that in just one case (Chap. XVII 170) a different reading from the new Siamese printed edition has been adopted.
