Introduction to the Tathagata Hall of Omniscience: The Tathagata Hall of Omniscience, Langpa Langze Lakhang, is the oldest among the three halls and has the most unique shape. The entire hall is in the shape of a multi-sided "Ya" character, which is actually a large mandala (mandala). The door faces east and north, covering an area of 2594.75 square meters (53.5 meters long from east to west and 48.5 meters wide from north to south). The central square hall symbolizes Mount Sumeru, the four groups of small halls in the four directions represent the four major continents respectively, and the four towering small towers at the four corners represent Langze Lakang, which is dedicated to the Tathagata, the omniscient being.
