59 He says much the same to his pupil Paula: Tell me whether you know of anything more sacred than this sacred mystery, anything more delightful than the pleasure found herein? What food, what honey could be sweeter than to learn of God's Providence, to enter into His shrine and look into the mind of the Creator, to listen to the Lord's words at which the wise of this world laugh, but which really are full of spiritual teaching? Others may have their wealth, may drink out of jeweled cups, be clad in silks, enjoy popular applause, find it impossible to exhaust their wealth by dissipating it in pleasures of all kinds; but our delight is to meditate on the Law of the Lord day and night, to knock at His door when shut, to receive our food from the Trinity of Persons, and, under the guidance of the Lord, trample under foot the swelling tumults of this world. And in his Commentary on the Epistle to the Ephesians, which he dedicated to Paula and her daughter Eustochium, he says: "If aught could sustain and support a wise man in this life or help him to preserve his equanimity amid the conflicts of the world, it is, I reckon, meditation on and knowledge of the Bible."
