Bhutan

If you got to Bhutan, a country which is predominantly Buddhist, you will find a lot of monasteries. And in almost all of the monasteries you will find a tower where you have to climb a substantial number of very steep and narrow stairs to get to the top. You really have to put in a lot of effort to get to the top. An when you get to the top, what do you find? A prayer hall? A temple with a magnificent figure of Buddha? A silent place for meditation? No. All you find is nothing. Just an empty space under a roof with the beams and struts that shoulder the roof. Then why climb all these stairs to get to the top? Is it to impress upon you that all your efforts in this world are in vain? Or is it something else. Being on a tight schedule I couldn't find out why.
