Donât worry â the Kesslers know that parents canât possibly be perfect. But they do believe that imperfect parents can raise their children on the foundation of a perfect system: the laws of nature, in particular the principle of causality â that every action causes an equal and opposite reaction. The Kesslers show parents practical ways to teach their kids â from infancy to young adulthood â that negative actions cause negative results, and positive actions cause positive results, equipping them for happy and fulfilling lives at home and beyond. They also show parents how to avoid âthe love ambushâ â the âyou don't love me anymoreâ line used by children â by letting their children know their role is not to receive love from them but to keep them safe.
