If my siblings or I didn't behave, my father would admonish us by saying, "My precious lights, this type of conduct is not appropriate for you." And immediately, his words would put us back on track. When my father referred to us as "precious lights," he wasn't just calling us by endearing names. Rather, he was reminding us of our higher mission.
