For the rest, Jesus is also seen by those who dwell in cities and towns and villages—that is, by those who have an active way of life and its obligat… - John Cassian

This will be the case when every love, every desire, every effort, every undertaking, every thought of ours, everything that we live, that we speak, that we breathe, will be God, and when that unity which the Father now has with the Son and which the Son has with the Father will be carried over into our understanding and our mind, so that, just as he loves us with a sincere and pure and indissoluble love, we too may be joined to him with a perpetual and inseparable love and so united with him that whatever we breathe, whatever we understand, whatever we speak, may be God.
In him we shall attain, I say, to that end of which we spoke before, which the Lord longed to be fulfilled in us when he prayed: ‘That all may be one as we are one, I in them and you in me, that they themselves may also be made perfect in unity.’ (John 17:22-23)

This prayer, then, although it seems to contain the utter fullness of perfection inasmuch as it was instituted and established on the authority of the Lord himself, nonetheless raises his familiars to that condition which we characterized previously as more sublime. It leads them by a higher stage to that fiery and, indeed, more properly speaking, wordless prayer which is known and experienced by very few. This transcends all human understanding and is distinguished not, I would say, by a sound of the voice or a movement of the tongue or a pronunciation of words. Rather, the mind is aware of it when it is illuminated by an infusion of heavenly light from it, and not by narrow human words, and once the understanding has been suspended it gushes forth as from a most abundant fountain and speaks ineffably to God, producing more in that very brief moment than the self-conscious mind is able to articulate easily or to reflect upon. Our Lord himself represented this condition in similar fashion in the form of those prayers that he is described as having poured out alone on the mountain and silently, and when he prayed in his agony he even shed drops of blood as an inimitable example of his intense purpose.

Thus we shall penetrate its meaning not through the written text but with experience leading the way. So it is that our mind will arrive at that incorruptible prayer to which, in the previous discussion, as far as the Lord deigned to grant it, the conference was ordered and directed. This is not only not laid hold of by the sight of some image, but it cannot even be grasped by any word or phrase. Rather, once the mind’s attentiveness has been set ablaze, it is called forth in an unspeakable ecstasy of heart and with an insatiable gladness of spirit, and the mind, having transcended all feelings and visible matter, pours it out to God with unutterable groans and sighs.
