The key to the kingdom of heaven is prayer. He who uses this key as he should sees what blessings the kingdom holds in store for those who love it. He who has no communion with the kingdom gives his attention merely to worldly matters.
To beginners the law of prayer is burdensome, like a despotic master; but to the more advanced it is like an erotic force, impelling those smitten by it as a hungry man is impelled towards a rich banquet.
~Ilias the Presbyter
