A good practice, and one that is encouraged by Spiritism, is to get the family together one night a week, the same night and at the same time, each week. We do, we start out with a prayer, then we use any of the books on Spiritism and read, taking turns, paragraphs of the section you will study that night. We particularly like the book, Jesus in the Home. Don’t hesitate to stop after an interesting passage and discuss a subject. Going off in tangents is no harm either. With children, let them free associate and wander where the concepts take them. You never know, we have had some of the best laughs during these sessions.
Take at least 30 minutes. Have a family prayer afterwards. It will serve as an introduction to Spiritism for the children and let them know the importance of God in their lives.
