If we want the devotees to be focused on the Deities we have to glorify the Deities. Besides establishing that goal there is also a need to remind the devotees of their connection to that goal. Kali Yuga means that there is a tendency to forget. Why is there quarrel (one of the symptoms of Kali Yuga)? Because people forget what the goal is. We have to keep reminding each other what the goal of our service is.
