Budai

Budai (Chinese:Bu Dai ), pronounced Hotei in Japanese, also known as the Laughing Buddha, was a Buddhist monk in China. Many Chinese Buddhists believe he was a reincarnation of Maitreya, the person who will become the next Buddha after Gautama Buddha.
He has become incorporated into Buddhist, Taoist and Shinto. Images of him can be found in many temples, restaurants, and businesses. Budai has become a god of happiness and plenty in some forms of Taoism and Buddhism. In Japan, Hotei is one of the Seven Lucky Gods (Shichi Fukujin). He is almost always shown smiling or laughing, hence his nickname in Chinese, the "Laughing Buddha" (Chinese:Xiao Fo ).
History
As Angida Arhat
Budai may be based on a monk that lived in the time of Sakyamuni Buddha. This monk's name was Angida, whose name means calico bag. According to legend, Angida was an Indian snake catcher who caught poisonous snakes to stop them from biting people. Budai and Angida look similar because they are both depicted as plump, laughing and carrying a bag.
As a Chinese Buddhist monk
In the Chinese tradition, Budai was a monk who lived in China around 907 to 923 CE. He was a man who was good and loving. Apart from his character, his likeness with the Maitreya Bodhisattva (the future Buddha) come from a Buddhist hymn (Chinese: Jie Yu ; Pinyin: Jieyu) which he said before his death:
Mi Le Zhen Mi Le ,Hua Shen Qian Bai Yi ,Shi Shi Shi Shi Ren ,Shi Ren Zi Bu Shi
Maitreya, the true Maitreyahas billions of incarnations.
Often he is shown to people at the time;other times they do not recognize him.
Description
Budai is almost always shown carrying a sack, which never empties, and is filled with many precious things, including rice plants (symbolizing wealth), sweets for children, food, and the sadness of the world. His duty is to protect the weak, the poor and children.
In Chinese Buddhist temples, Budai's statue is put in the front part of the entrance hall. He is shown as a stout, smiling or laughing man in robes with a largely bare belly, which represents happiness, good luck, and plenty.
Some statues show small children at his feet. Another item that is usually seen in Budai statues, is a begging bowl, which shows that he is a Buddhist. All of these images show Budai as a wandering monk who goes around and takes sadness from people. Because he represents richness and happiness, statues are often found in homes and businesses in China and Japan.
Chan Buddhism
The main story that concerns Budai in Chan is a short koan.
Phra Sangkadchai/ Phra Sangkachai
In Thailand Budai is sometimes confused with another monk that is respected in Thailand. Phra Sangkadchai or Shanghai (Thai: phrasangkacchcchaayn), a Thai spelling of Mahakaccayanathera (Thai: mhaakacchcchaaynethra), was a Buddhist monk in the time of the Buddha. The Buddha praised Phra Sangkadchai for his excellence in explaining complicated dharma (or dhamma) in an easily understandable way.
Although both Budai and Phra Sangkadchai may be found in both Thai and Chinese temples, Phra Sangkadchai is found more often in Thai temples, and Budai in Chinese temples. Two points to distinguish them from one another are:
1. Phra Sangkadchai has a bit of hair on his head while Budai is bald.2. Phra Sangkadchai wears the robes in Theravadin Buddhist fashion with the robes folded across one shoulder, leaving the other uncovered. Budai wears the robes in Chinese style, covering both arms but leaving the front part of the upper body uncovered.
Folklore
One belief surrounding the figure of Budai in popular folklore is that if a person rubs his belly, it brings wealth, good luck, and prosperity. This belief however is not part of any Buddhist ritual, but is a part of a Chinese folk belief. He is often admired for his happiness, abundance, wisdom, and contentment.
