Patti did pray for a miracle and she certainly received one. It was a current of grace that eventually moved across the world.
To prepare for her retreat she prayed, fasted and was docile to the Holy Spirit. She and all the other retreatants were instructed to read the first four chapters of the Book of Acts in the Holy Scriptures and also the book The Cross and the Switchblade by David Wilkerson.
Patti's prayer was, "Lord, ... I believe I already received your spirit in Baptism and Confirmation, but if it is possible to receive more, I want it."
She and those on the Duquesne week-end retreat invoked the Holy Spirit with the hymn "Veni Creator Spiritus".
Come, Holy Spirit, Creator blest, and in our souls take up Thy rest; come with Thy grace and heavenly aid to fill the hearts which Thou hast made. O comforter, to Thee we cry, O heavenly gift of God Most High, O fount of life and fire of love, and sweet anointing from above. Thou in Thy sevenfold gifts are known; Thou, finger of God's hand we own; Thou, promise of the Father, Thou Who dost the tongue with power imbue. Kindle our sense from above, and make our hearts o'erflow with love; with patience firm and virtue high the weakness of our flesh supply. Far from us drive the foe we dread, and grant us Thy peace instead; so shall we not, with Thee for guide, turn from the path of life aside. Oh, may Thy grace on us bestow the Father and the Son to know; and Thee, through endless times confessed, of both the eternal Spirit blest. Now to the Father and the Son, Who rose from death, be glory given, with Thou, O Holy Comforter, henceforth by all in earth and heaven. Amen.
In addition, they also had a penance service at the retreat where they repented of their sins. This opened them up to receive the great outpouring of the Holy Spirit.
Patti continued to pray, "Jesus be real to me." She told the Lord, "I give my life to you, whatever you ask of me, I accept it, and if it means suffering, I accept that too. Just teach me to follow Jesus and to love as He loves."
Patti's example is one to follow. Invoke the Holy Spirit, pray and fast. Repent. Ask for more. Expect a miracle. And see what happens.
