Soul

 Soul is non-material, and unmeasurable. It is not something that can be won or bought or sold. Soul isn't a reward that someone gives me if I am good enough, or an accolade I earn by being smart enough, or an object I can buy when I am rich enough. Soul is that place where all the waters meet, where giving and receiving are one, where forgiveness and release happen, and where ego and vanity disappear. Where soul thrives, selfishness does not, and where selfishness thrives, soul does not.
