Every detail of Wat Rong Khun carries deep religious symbolism – though admittedly most Thais will be unaware of most of the meaning as well unless they have studied up on its mysteries. Departing from the expected gold, Chalermchai chose to construct the temple in white, symbolizing the purity of Lord Buddha. The mirrors embedded in the structure reflect light, representing the Buddha’s wisdom shining out across the Earth and the Universe.
