Lu-Tse's yearbook of enlightenment - Terry Pratchett

Lu-Tze is a senior History Monk, also known as Sweeper. Although thought to be 800 years old, there are some who claim he is older yet . . . 5,200 years older, in fact, because for the History Monks, time is a resource to manipulate, and they do . . .
Lu-Tze, a bald, yellow-toothed little man with a wispy beard, has a faintly amiable grin, as if constantly waiting for something amusing to happen, and a handy epithet for every occasion. In his life, Lu-Tze has done everything, and his past deeds are legend amongst the History Monks. He is a follower of The Way of Mrs Marietta Cosmopilite. He also grows Bonsai mountains.
LU-TZE'S YEARBOOK OF ENLIGHTMENT (including The Way of Mrs Cosmopilite) is the ideal companion for those seeking truth and harmony and, well, the meaning to life - though he doesn't guarantee it will be the right meaning . . .
