What it means: Adoration. Reverence. Worship. A readiness to seek your purpose in the priorities of another. A love that transcends the rational.
An example:
“Beside me, on the left hand, appeared an angel in bodily form… In his hands I saw a great golden spear, and at the iron tip there appeared to be a point of fire. This he plunged into my heart several times … and left me utterly consumed by the great love of God.”
—St. Teresa
