While we are sitting in meditation, we are simply exploring humanity and all of creation in the form of ourselves. We can become the world’s greatest experts on anger, jealousy, and self-deprecation, as well as on joyfulness, clarity, and insight. Everything that human beings feel, we feel. We can become extremely wise and sensitive to all of humanity and the whole universe simply by knowing ourselves, just as we are.
