"His last words to his followers were in a sermon on the previous Sunday. Rhygyfarch transcribes these as 'Be joyful, and keep your faith and your creed. Do the little things that you have seen me do and heard about. I will walk the path that our fathers have trod before us.' 'Do the little things in life' ('Gwnewch y pethau bychain mewn bywyd') is today a very well-known phrase in Welsh, and has proved an inspiration to many."
