Teresa of Avila regarded Mary as the mother of Carmelites

"His Majesty (God) well knows that I can only pride myself of His mercy, and since I cannot deny my past, I have no other remedy than to rely on Her, to trust in the merits of her Son and of the Virgin, his mother, whose habit, which you also wear, I unworthily wear.

Praise Him, my daughters, for being truly the daughters of this Mother Mary; you have no reason to be ashamed of my misery, since you have such a good mother.

Imitate her, consider how great this Lady must be, and how happy we are to have her as our patroness, since my sins and the fact that I am what I am in no way discredit this holy Order.

But I warn you of one thing: although daughters of such a mother, don't be too sure of yourselves, for David was very holy, and you see how Solomon was. Do not presume upon the monastic enclosure and your life of penance." (The Interior Castle, 3rd Dwellings, chap. 3-4)

"Let us keep the Rule of Our Lady of Carmel ... may it please the Lord that everything be for his glory and praise, and that of the glorious Virgin Mary, whose habit we wear." (Autobiography 36,26 and 28)
