When my son was two years old, he played like most toddlers I’ve known. He built block towers and yelled in frustration when they toppled down. He climbed every structure at our neighborhood park and protested when it was time to leave. He complained when a beloved toy stopped working, broke, or the batteries ran dry. I decided, half-jokingly, that I would try to teach him the Buddhist Law of Impermanence—the notion central to Buddhist teaching that things change and nothing lasts forever. I suggested to my husband and other parents, with a strong dash of humour, that this law would ease our children’s sense of loss or disappointment, which would only intensify as their lives progressed. I do not claim to be a master of Buddhist thought, but it did occur to me that if our children were to know and accept the Law of Impermanence at a young age, it would increase their chances of living happy lives.
