Here, Dom Augustin Guillerand teaches us something about entering the chamber, shutting the door, and praying to our heavenly Father in secret (cf. Matthew 6:6). This is important for all types of prayer. Many of us, for example, can probably relate to praying a Rosary, but it is not until arriving at the second or third decade that we finally are attuned to God. Here are his words:
Prayer is, as it were, being alone with God. A soul prays only when it is turned towards God, and for so long as it remains so. As soon as it turns away, it stops praying. The preparation for prayer is thus the movement of turning to God and away from all that is not God. That is why we are so right when we define prayer as this movement. Prayer is essentially a “raising up,” an elevation. We begin to pray when we detach ourselves from created objects and raise ourselves up to the Creator.
Now this detachment is born when we clearly realize our nothingness. That is the real meaning of our Lord's words: “He that shall humble himself shall be exalted” (Matthew 23:12). His whole life was a continual abasement, always more and more profound. Saint Bernard does not hesitate to say that such an abasement brings us face to Face with God. Hence the peace of souls that have fallen when, raised up by God, they find themselves in His presence. And it is precisely in their abasement, once they have recognized and admitted it, that they find him, because it is there He reveals Himself. The only thing that prevents Him from doing so is our “self.” When we own to our nothingness, this “self” is broken down, and once that happens the mirror is pure, and God can produce His own Image in the soul, which then faithfully reproduces His features that are revealed in all their harmony and perfect beauty.
It is this our Lord meant in that vital passage in the Sermon on the Mount, and that all human considerations on prayer repeat endlessly but without arriving at its full splendor: But thou, when thou shalt pray, enter into thy chamber and, having shut the door, pray to thy Father in secret. Enter this sacred chamber of your soul and there, having closed the door, speak to your Father, Who sees you in these secret depths, and say to Him: Our Father, Who art in heaven.... This intimate presence; your faith in Him Who is the secret depth of it and gives Himself there; the silence towards all that is not God in order to be all to Him - here is the preparation for prayer.
It is obvious that we do not reach such a state of soul without being prepared for it by quite a combination of circumstances. And this is just what we do not know sufficiently in practice. The way to prepare for prayer is by leading a divine life, and prayer, after all, is that divine life. Everything that reproduces God's image in us; everything that raises us beyond and above created things; every sacrifice which detaches us from them; every aspect of faith which reveals the Creator to us in creatures; every movement of true and disinterested love making us in unison with the Three in One -- all this is prayer and prepares us for a still more intimate prayer. All this makes the divine word of the Sermon on the Mount real and the dual movement it recommends: Shut the door, and pray to thy Father. When he spoke thus, the divine Word showed that He knew our being and its laws. He revealed Himself as our Creator and made Himself our Redeemer. He showed that He made us and that He alone can re-make us.
We do not suffice to ourselves; we have not that in us which can complete us; we need to be completed. I know I am putting it badly when I say that this complementing thing is not in us. Actually, it is within us, but it is in a part of us which is, as it were, outside of us. In us as in God, there are many mansions. God is within us in the depths of our soul, but by sin we no longer occupy those depths. When Eve looked at the forbidden fruit and stretched out her hand to take it and eat it, she went out of those secret depths in her soul. It was these depths which were the real terrestrial Paradise, where God visited our first parents and spoke to them. Since the Fall, God is in us, but we are not!
The preparation for prayer consists in returning to those depths. Renunciation, detachment, recollection -- whatever word we use, the reality is the same, and that reality is the true secret of prayer. Close the door, and enter. . . . It needs only these two phrases to explain this, but in reality they are only one thing. They represent a movement, for all that unites us to God is movement. The words are related to two ‘terms’ or ends. If we speak of the terminus a quo (that is, from), they say (and they do what they say): Close. If we think of the terminus ad quern (that is, to), they say: Enter. We have to close the door on all that is not, and enter into Him Who is. There you have the secret of all prayer.
