Hui Gong, also known as Hui Gong, means to get together.

During the offering, the practitioners gather in one place, offer offerings together, and try their best to concentrate together. It is easy to understand that collective practice can arouse confidence in practice more than individual practice. Generally speaking, offering alms can produce greater results than practicing dharma alone in the room. This is the meaning of offering.

offering is a ritual by which believers pray for blessings or assistance from the guru and the buddhas and bodhisattvas. Holding an offering can clear the obstacles in the world, internal obstacles and secret obstacles, as well as the adverse fate of the achievements in the world.

World barriers affect daily life, including interpersonal relationships, business and so on; Obstacles hinder physical and mental health; Secret barriers hinder our true wisdom. Donation can also be used to turn over the dead, make them feel peaceful, and lead them to incarnate the good way until they are liberated and enlightened.

Extended information:

In front of the clean Buddhist temples and altars, offerings such as gallnuts, fruits and flowers were placed, which were blessed by monks with virtue and other monks, and were transformed into infinite and wonderful offerings, welcoming all the people in the pure land and holy land to inherit the enlightened guru, the silent and angry Buddha, and the courage.

Repent the sins you have committed since you started, such as breaking samadhi precepts (oaths), and pray for the elimination of all karma, such as illness, disaster, troubles and knowledge, so as to temporarily achieve the blessing of all people's wishes in the world (such as the growth of happiness, smooth career, elimination of obstacles, and getting rid of magic difficulties), and finally achieve the fruit of holding the position of Ming (Buddha and Bodhisattva).
