To salute s.o.; to shake hands and touch one’s forehead and breast.
The lesser in status or younger one takes one or both hands of the one he is saluting in his one or two hands, lightly touching them, then both parties touch their own foreheads and chests, or nowadays just the chest. This is done in greeting and after a ceremony has been performed, e.g. after prayers.
How much money (did you press in his hand) when you saluted him?
