"Yet sometimes the mind which advances to that true disposition of purity and has already begun to be rooted in it, conceiving all of these at one and the same time and rushing through them all like a kind of ungraspable and devouring flame, pours out to God wordless prayers of the purest vigor. These the Spirit itself makes to God as it intervenes with unutterable groans, unbeknownst to us, conceiving at that moment and pouring forth in wordless prayer such great things that they not only—I would say— cannot pass through the mouth but are unable even to be remembered by the mind later on."
