The Carmel encourages humility as Mary understood it

To become humble of heart as Jesus desires, there are no recipes, no secrets; there is no need for expert approaches or steps. It would do no good to think of oneself as more despicable, more rebellious or more unworthy than one is; and sometimes too much self-effacement can hide a subtle self-centeredness.

In Carmel, humility remains simple, lively, and joyful, because that is how Mary understood it. In Carmel, humility is a kind of transparency to God and to oneself, which allows one to say to God, without anguish or sadness: "Yes, I am that, I am only that, and this is where I am; but as I am, I am your child, and that is enough for my happiness. My misery will not prevent me from loving you today, from serving you only for today, since tomorrow belongs to you alone.”

We need to remain transparent to others also, because, once a daughter of Saint Teresa is truly committed to the "Ascent", she no longer has a role to assume, whether it be flattering or not; no persona to defend, and no mask to keep in order to protect her self-image. The humility of Carmel is the filial patience of those who bend to the rhythm of the Spirit, who are not afraid of being caught in the shadow of the Most High, and who know how to wait, like Mary in Nazareth, for the hour when God will speak.

Happy the Carmelite who believes, despite the unpredictable turns of God's ways, that there will be "a fulfillment of all that has been spoken to her from the Lord". The Father, who sees what is done in secret, knows all her efforts; the Spirit who fills the universe perceives every word, hears every call that rises from a poor heart; therefore love must banish all fear: weariness may come, certainties may recede, hope may be shaken in times of turmoil, but God will always cast his eyes on the humility of his servant.
