The soul is like wax that, placed in the sunlight, melts for love of the ray that his Majesty infuses in it. Humility gives the soul strength to persevere, making known to it that as wax hardens when removed from the sunlight, so the soul, turning from God, will become hard again and lose the recollection and tender love it received from the Lord.
–Francisco de Osuna (1497-1541)
