The correct use of a fly swatter

Carrying on filling in Facebook surveys during idle moments I moved onto Chinese Philosophers and ended up as Lin-Chi (Linji) who lived during the Tang Dynasty and died in 866 AD. He formed the Linji school of Chán Buddhism. His method to help students attain enlightenment was to yell at them and strike them abruptly with a fly-swatter, so as to shock them into a religious experience. For good measure the America folk hero I resemble is John Henry known for beating the steam hammer at hammering rail spikes, and holes into rock, so there is obviously a pattern here that some may recognise.
