"Know that when you do not possess calm, you do not have humility within you. The Lord revealed this in the following words, which indicate as well where to seek after calm. He said: “Learn of me, for I am meek and lowly of heart, and ye shall find rest unto your souls” (Matthew 11:29)." -- Advice from the Holy Elder St. Leo (Nagolkin) of Optina
St. Alexius strongly cared about his flock, organized monasteries, and built relationships with the Kahn's Golden Horde. In 1357 Khan demanded that the Grand Duke send the saint to him in order to heal the blind Taydulu, his wife. "The petition and the case exceeds the measure of my strength" said St. Alexius "but I believe in One who gave his sight to the blind. He will not despise a prayer of faith." And indeed, by his prayer and sprinkling of holy water, the wife of the Khan was healed.
