Hinduism in Thailand
Thai culture is more Sanskrit than its Buddhist surface lets on. The king's name, Vajiralongkorn, means "thunderbolt ornament". Even Bangkok's ceremonial name ends by invoking Vishvakarman, the Hindu god of craftsmen.
Thailand is overwhelmingly Theravada Buddhist by census, yet the Hindu layer is everywhere once you know where to look. Royal coronations are performed by Brahmin priests — the Rajaguru lineage — whose line traces back through the Khmer Empire to southern India. The ceremony that makes a king is Hindu; the country he rules is Buddhist.
The Erawan Shrine
Perhaps the most visible Hindu site in Bangkok sits on a traffic-heavy corner outside the Grand Hyatt. The Erawan Shrine houses a statue of Phra Phrom — the Thai form of Brahma, the four-faced creator. Built in 1956 to end a string of construction accidents at the adjacent hotel, it became a place of daily offerings within a generation. Buddhist devotees pray there in numbers that a stricter reading of Buddhism would find strange.
The Ramakien
The Ramayana, India's great epic, arrived in Southeast Asia over a thousand years ago and became the Thai national epic as the Ramakien. The Thai version bends the story: Rama becomes a bodhisattva, Hanuman's character shifts, and the moral universe tilts away from strict dharma toward something closer to Buddhist forbearance. Scenes from the Ramakien line the walls of Wat Phra Kaew — the temple of the Emerald Buddha inside the Grand Palace.
A braided religion
The working theory of scholars is that Thailand's religion is not Buddhism-plus-Hinduism but a single hybrid system inherited from the Khmer Empire, where the kings of Angkor claimed to be devaraja — god-kings — through both traditions at once. When Theravada Buddhism became dominant in the thirteenth century it absorbed the apparatus rather than replacing it. A Brahmin still consecrates the monarch; a spirit house still stands beside the office tower; and Bangkok's ceremonial name still ends with a line about the god Vishvakarman establishing the city.
