(The lone Monk)
The monk leads chants which are usually about the 8 precepts of being a good Buddhist and the people repeat his words. Sometimes you see all the people touching each other while a person pours water from a cup into a bowl and this is done while the monk is saying a vow/prayer. This is meant to be creating holy water and the people all touching the person who is pouring the water is also receiving the goodness as well and this is creating something like a prayer line and all the good is passed through each person who is connected. You see this happen a lot during ceremonies.
