It seems that the bigger the house or institution the larger the spirit house erected outside of it. Once a spirit house has been purchased it needs to be put in place. Interestingly enough, the spirit house is not put in place by Buddhist monks as one may think. Rather this is a rite performed by the Brahmans. Brahman priests look totally different from Buddhist monks.
Brahman priests dress in all white and have a knot of hair at the nape of their neck.
Buddhist monks have shaved heads and saffron, yellow or orange robes. There are currently about ten Brahman priests living in Bangkok. They are attached to the Royal Court and can be seen at all Royal Ceremonies. Brahmanism itself is an ancient religion from India and is both a predecessor and contributor to Buddhism and Hinduism. It can also be classified as Orthodox Hinduism.
