I forgot to include another point from the radio.
Apparently, part of the indoctrination process is self-indoctrination. This includes mind-numbing repetions of chants and mantras, such as "Hare, Hare Krishma," etc.
In a WT field service context, perhaps this might include such mantras as, "Would you like to live forever in paradise?" or " Have you ever wondered about the kingdom that Jesus taught us to pray for?" In the course of a single morning, these get repeated over and over again until they're repeated on auto pilot, without thinking.
At meetings it might perhaps be mantras like, for children, "God's name is Jehovah," or "Paradise." For adults, "Wasn't that a wonderful meeting?" or "Brother So-and-So's a marverllous speaker, isn't he?"
However, whatever the mantra, the end result is the same: self-indocrtrination.
