Group involvement is a key factor. The methods used are highly participatory teaching techniques using role plays, stories, songs, visuals, demonstrations, and large and small group discussions. Volunteers go through 40 – 50 sessions, each including a physical/health and spiritual/moral value lessons. The training is spread over three to six months. Each day they receive one physical and one spiritual subject. They then put into practice what they have learned as they visit in neighbors’ homes. After the initial training is completed, they receive two to three days each month of additional training for the next twelve months.
