"Opening our heart also means to express love. Rupa Gosvami describes in Sri Upadeshamrita that offering gifts and revealing one’s mind in confidence are exchanges of love. Therefore, an open heart means to be open to having loving exchanges. However, there cannot be loving exchanges when we always think, “What are they going to do for me?” There is no love in that; it is business. Loving exchanges can only exist when we think about keeping our hearts open—“How can I serve others?” Having an open heart means being eager to serve others.
