Then he should supplicate something what he wishes.
After that, he should pay homage to them and go back from them taking four or five steps backward and with joined-palms on his forehead, without turning his back to them.
One who pays homage physically to the Buddha and the Samgha has to touch the ground or the floor with five parts of one's body. These five parts of body are: forehead, two hands and two knees. This is called the five fold manner of touch.
When a Buddhist meets the members of the Samgha on the way, he should stop his stepping, take off his head-wear and shoes. Then he should raise his joined-palms on his forehead with his body leaning forwards.
