In her book HANA'S INNER TEACHER
The author has been interested in children's behavior since beginning working with children in elementary schools and then continued through the middle and high school. One of the scientific ideas she taught her students is that

everything is energy. Our moods and feelings are energies that we are "sharing" with all living things wherever we

go. Our energies do affect others and, other people's energies affect us somewhat. So we need to be aware

of how we feel. We can decide to protect ourselves every morning when we wake up by ignoring bad moods and by making a ball of energy around ourselves. This story tells how Hana realized she could be in better moods when she could simply take care of her own feelings.
