Entering the Spiritual Center of NE Thailand and Lao at sunset is very special, since in addition to being in awe of the massive stupa that dominates the whole complex, the monks at Wat Phra That Temple are conducting their evening chanting.
Three walls surround the sacred pagoda at Wat Phra That Phanom. Upon entering the second wall, everyone takes off their shoes. People enter the second wall, bow down and show their respect to the Buddha. Frequently people will then do a walking meditation of circling the stupa three times.... first to show their respect to the Buddha, second to the Dhamma or the Buddha's teachings and third, to the sanga, or the community.
The third or last wall can not be entered. Walking up to the brightly painted red door in the third wall is as close as one can get to the actual pagoda.
