today i'm heading off on a hike up to one of the most sacred monasteries in bhutan. it's called tiger's nest, and my guide karma will be leading the way. what mecca is to muslims, tiger's nest is to the bhutanese. on my 90-minute trek to the monastery, at every turn i am met by prayer. i pass stream-powered prayer wheels and prayer flags which, on the back of the wind, deliver their constant blessings to the world. besides the thousands and thousands of prayer flags that fly all over bhutan, there are also prayer wheels. they can be powered by water, they can be powered by wind, and they can also be manually powered. on the wheel is the sanskrit inscription "om mani padme hum," one of the sacred mantras. so you spin it in a clockwise direction, repeating over and again, "om mani padme hum, om mani padme hum." so it's an instrument of meditation as well as an instrument of prayer. you know what they say? >> yeah. >> "journey of a thousand miles begins with one step." >> one step. yeah, sure. >> these are many. >> yeah. >> many steps towards enlightenment. >> yes, many
