Salutation.
Another way of dispelling evil spirits is by the various forms of salutation, which generally consist in the invocation of some deity. The Hindu says, “Râm! Râm!” when he meets a friend, or Jay Gopâl! “Glory to Krishna!” or whoever his personal god may be, and the same idea accounts for many of the customs connected with the reception of guests, who, coming from abroad, may bring evil spirits with them.
