Zen?

These raked rock gardens are part of the Zen buddhist philosophy. Aparantly they help the devotees calm their minds and achieve better meditation. However on the day I visited, they were mostly surrounded by hoards of Japanese and other multinational tourists. I cant say I achieved too many Zen thoughts whilst I was there but i was certainly impressed by the amount of work that must go into raking these gardens every morning. Not a foot print to be seen anywhere? How do they do it?
