We can relate to these emotions of the gopis, as they are based upon the emotions that we experience in relationships in this world. However, the emotions that we experience in this world are the perverted reflections of the emotions that the gopis and the residents of Vrindavana are experiencing with Krishna. The symptom of their love is that it is never diminished even though there is reason for it to diminish. It is one of the symptoms given by Rupa Gosvami as the criteria of loving relationships between Krishna and the gopis. Although there is a reason for diminution of their love, it is never diminished. Rather, it is always increasing.
