Chan Master Sheng-yen
Chan Master Sheng-yen is the Patron of the Western Chan Fellowship. He has led retreats at Maenllwyd in 1989, 1992, 1995, and on his last visit to the UK he led a retreat for 60 people at Gaia House in July 2000.
His teachings were recorded on each occasion, and the book Catching a Feather on a Fan contains the teachings from the 1989 retreat, and details of the retreat schedule, retreat reports by participants, etc. The teachings from the 1995 retreat were published in New Chan Forum Issue 15. The book Illuminating Silence: The Practice of Chinese Zen contains the teachings from the 1989 and 1995 retreats, together with additional material by John Crook.
