Once on the Nepal side the tension subsides and Tibetan Folk songs ring through the valley. Tibetans often whistle a tune that lulls Yak and herder into a meditation. The occasional, Ang Tashi, Ang Nima (yak names) echoing off the walls as the animals are persuaded to move faster.
On this trip I could hear the yak bells in the distance. A kind of soft sound making one forget the miles under feet.
