The main activities are in the afternoon of the first day, when an important Buddha image named Fon Saan Haa (literally one hundred thousand drops of rain) is taken from Wat Chedi Luang and paraded around Chiang Mai city, while local people sprinkle it with lustral water. The belief behind this is that those who take part in the ceremony will be blessed with good health and that rain will fall in the right at the right time of the season. The parade ends at Wat Chedi Luang where the seven days of Inthakin is held.
The crux of the Inthakin Festival revolves around a ceremony called Tam Boon Khan Dok – the way of merit-making by offering flowers, candle, and joss sticks in the bowls in teh front of the temple. Each evening, monks chant prayers and sprinkle lustral water, and bestow blessings on flok performances, such as the playing of the Saw, a Thai classical instrument, and the dancing of the Lance Dance, the Sword Dance, and the Muang Dance.
The rite of the Tham Boon Muang, the city merit-making ceremony, is observed at each of the four gates to the city, and each of the four corners of the ancient walls inside the city moat.
