Comment on the invocation at the beginning of the play?

The play opens with a prayer ritual performed by Hindus to the god Ganesha, who has the head of an elephant and the body of a boy. Bhagavata asks that Ganesha bless the performance that he and the assembled company are about to perform, and then tells the audience that the play is set in Dharmapura, and the central characters are close friends Devadatta and Kapila.
