Here is an excerpt by Frank Duff from "Can We Be Saints"
Devotion to Mary....
You must have a tremendous love for Mary. Read and pray, and pray again, until you get that love. Implore Our Lord to give you just the love for her that He would wish you to have. A great love for her is a great sign of sanctity. Do not treat her only as the Queen of all Saints. She is much more than that. She is the most beloved Daughter of the Father, the Mother of the Son, and the Spouse of the Holy Spirit. When you pray to any one of these Three Divine Persons, let her be near to recommend your prayer. And she is also our Mother. Is this idea real to us? The love of our own dear earthly mothers is a wonderful thing. What seas of fire and water would they not go through for us! Yet their love is faint and weak compared with hers.
There is a beautiful traditional custom which unhappily seems less common than it was - the consecration of babies by their parents to this Blessed Mother. The terrible power of the Evil One over the bodies of people possessed by him should be the best recommendation of this Devotion. More than he can do for evil, a million-fold she can do for good. Let us consecrate to her not only our children, but ourselves in the most solemn manner - remembering that what belongs to Mary is all for Jesus.
