...It is interior, trustful, holy, constant and disinterested.

First, true devotion to our Lady is interior, that is, it comes from within the mind and the heart and follows from the esteem in which we hold her, the high regard we have for her greatness, and the love we bear her.

...it fills us with confidence in the Blessed Virgin, the confidence that a child has for its loving Mother. It prompts us to go to her in every need of body and soul with great simplicity, trust and affection.
We implore our Mother's help always, everywhere, and for everything.
We pray to her to be enlightened in our doubts,
to be put back on the right path when we go astray,
to be protected when we are tempted,
to be strengthened when we are weakening,
to be lifted up when we fall into sin,
to be encouraged when we are losing heart,
to be rid of our scruples, to be consoled in the trials, crosses and disappointments of life.

...true devotion to our Lady is holy, that is, it leads us to avoid sin and to imitate the virtues of Mary. Her ten principal virtues are:
deep humility,
lively faith,
blind obedience,
unceasing prayer,
constant self-denial,
surpassing purity,
ardent love,
heroic patience,
angelic kindness,
and heavenly wisdom.

...true devotion to our Lady is constant. It strengthens us in our desire to do good and prevents us from giving up our devotional practices too easily. It gives us the courage to oppose the fashions and maxims of the world, the vexations and unruly inclinations of the flesh and the temptations of the devil. Thus a person truly devoted to our Blessed Lady is not changeable, fretful, scrupulous or timid. We do not say however that such a person never sins or that his sensible feelings of devotion never change. When he has fallen, he stretches out his hand to his Blessed Mother and rises again.
