What is Love?

"Falling in love, being an emotion, is not eternal. The emotion of love must be purified in other words, falling in love must become true love; it must involve the will and the mind in a journey of purification, of greater profundity so that it is truly all of man, with all his capacities, with the discernment of reason and the force of will, who says: ‘Yes, this is my life’” ~ Pope Benedict XVI
