Origen on prayer

"Since therefore it is so great an undertaking to write about prayer, in order to think and speak worthily of so great a subject, we need the special illumination of the Father, and the teaching of the first born Word himself, and the inward working of the Spirit, I pray as a man—for I by no means attribute to myself any capacity for prayer—that I may obtain the Spirit of prayer before I discourse upon it, and I entreat that a discourse full and spiritual may be granted to us and that the prayers recorded in the Gospels may be elucidated." (On Prayer, Ch. 1)

This reminds me of the Book of Wisdom: "For what man knows God's counsel, or who can conceive what our LORD intends? For the deliberations of mortals are timid, and unsure are our plans. For the corruptible body burdens the soul and the earthen shelter weighs down the mind that has many concerns. And scarce do we guess the things on earth, and what is within our grasp we find with difficulty; but when things are in heaven, who can search them out? Or who ever knew your counsel, except you had given Wisdom and sent your holy spirit from on high? And thus were the paths of those on earth made straight, and men learned what was your pleasure, and were saved by Wisdom." (Wisdom 9:13-18)

And Bonaventure's Itinerarium: "Therefore to the cry of prayer through Christ crucified, by Whose blood we are purged of the filth of vice, do I first invite the reader, lest perchance he should believe that it suffices to read without unction, speculate without devotion, investigate without wonder, examine without exultation, work without piety, know without love, understand without humility, be zealous without divine grace, see without wisdom divinely inspired. Therefore to those predisposed by divine grace, to the humble and the pious, to those filled with compunction and devotion, anointed with the oil of gladness [Ps., 44, 8], to the lovers of divine wisdom, inflamed with desire for it, to those wishing to give themselves over to praising God, to wondering over Him and to delighting in Him, do I propose the following reflections, hinting that little or nothing is the outer mirror unless the mirror of the mind be clear and polished." (Prologue 4)
