You may be asking yourself what the point is there to diving or falling intentionally down a flight of stairs. The simple answer is that there is no point, that one throws themselves down a flight of stairs simply to entertain others. A good laugh from a crowd can be an exhilarating moment. The longer answer is that there are some deep philosophical reasons behind this seemingly pointless act of madness. Nothing illustrates better the Zen principles of cause and effect than a controlled plunge down a staircase. One’s clarity of mind while in motion is almost soothing, completely transfixed on the moment. Afterwards, the pain reminds one of their humanity and the how ethereal our bodies truly are.
