What is defilement? What is undefiled joy? How do we free ourselves from defilement and attain undefiled joy? Brother Yang summarized the second chapter of the Ten Grounds of Bodhisattvas on defilement. He used various lived examples to illustrate how our body and mind are a great liability for defilement, and what the differences between defiled and undefiled joy are. He closed by sharing how we can use a daily reflection journal to train ourselves and attain undefiled joy.
