I like the sacrifice beads too. I do not have a big devotion to St. Therese right now, but my mother did, St. Therese was her name saint (mom was named Rosemary Therese by her mom) and was canonized 6 months before Mom was born. Also, one of my favorite persons on the road to canonization, Rhoda Wise, had a big devotion to her and reported that she saw apparitions of her. I have been thinking of praying to St. Therese more because I would like to ask her something relating to my mom who is deceased now.
Here is the St. Therese prayer that Rhoda Wise used to give out to the pilgrims who wrote to her or visited her home.
O beautiful Rose of Carmel, Saint Therese of the infant Jesus, deign according to your promise to descend from Heaven to visit those who implore you, to pour down on us in profusion those Celestial Graces that are symbolized by the shower of roses that Jesus, your Spouse, has put at your disposal. Your Power is great with Jesus, assist me in this need (say your intention here). Speak for me to Jesus and to Mary and obtain for me the grace to live a holy life and die a happy death.
St Therese, hear my prayer. Show your power with God and help me, if it be for the honor of God and the good of my soul. Amen.
