Adam's Heart

Eve was not made out of a rib. Eve was taken from Adam's rib. In other words, Adam had his rib cage open so that his heart could be taken out and formed into his wife. Eve is his heart. Therefore, a man should cleave unto his wife and together they will be one flesh. Jesus' heart was also pierced after his flesh had been crucified. The pure water flowed out of His heart. When the flesh is overcome (remembering that Jesus' cross is easy, and His burden is light) the pure love of God flows through us.
