So far the children are concerned they should know simply four things: 1. Simply think of Krishna always, 2. become Krishna's devotee, 3. offer Krishna worship, 4. offer Krishna obeisances. These four things should be taught and everything else will follow nicely and they will be learned persons. Give them nice food, let them play. Some can be cowherd boys, some can be cows, like that. Play and take food and be Krishna Conscious. As soon as they begin playing they will be inspired, only one has to direct how to play, that's all. They should attend the regular aratis and dance before the Deities, just like the children are doing in Los Angeles, and there should not be separate special aratis for the children, although they may also learn how to do arati in the class before one picture. They must all go to bed by nine pm and arise at four am for mangala arati, and in day-time a little rest.
