Jokhang Temple is the spiritual center of Tibet. Everyday, pilgrims from every corner of Tibet trek a long distance to the temple. Some of them progress by prostrating themselves throughout their journey until they reach the threshold of the temple. Pilgrims kindle butter lamps with yak butter, or honor the deities with white scarves (Kha-btags or Hada) while murmuring sacred mantras to show their pieties to the Buddha.
