Among these images are several that illustrates the understanding that as Christ received his human nature from the most pure Virgin, so the Heart of Jesus and Mary are one. Both in image and in text they illustrate not two separate hearts, but rather one inseparable Heart of Jesus and Mary.


Door to the Sacred Heart
O, you who desire to establish your dwelling 
in the Heart of Jesus.   
Come, the Heart of Mary is the Door.
Letaille
The Heart of Jesus watches over the orphans.
Turgis, Paris pl. 107


Captioned as Heart of Jesus, but imaged as Heart of Mary, the card brings text and image together to illustrate the unity of the Heart of Jesus and Mary and the unity of all believers.
PURE LOVE
The degree of purity determines the degree of union.
"The supernatural union exists when God's will and the soul's will are in conformity.
Therefore the soul rests transformed in God through love...
The illumination of the soul and its union with God corresponds to its purity."
~St. John of the Cross Ascent of Mt. Carmel BK. 2 CH. 5
