Devotion to the Heart of the Savior, it must be repeated, is adoration of/and a relationship to the Person of Christ and His Heart, the Person with His Heart, the Person under the aspect of His Heart, the person from the point of view of His Heart-center, the Person through the symbol of His Heart, but never the Heart separated from the Person!

“Updated Devotion to the Sacred Heart” by Rev. Walter Kern 1975, page 20
