And maybe you haven't read this story about the power of only one Hail Mary.
You can pray all the hail mary's you wish. They will get you no closer to God's throne! There is only one mediator, and that is Jesus Christ. All of your dead saints equal a bunch of rotten corpses. They cannot gain God's ear any more than , indeed, they cannot even speak for themselves now! They are dead in Christ, or not! If they relied on their RCatholicism for their salvation, I am not holding much hope for them!
As for "praying the lord's prayer but once...", Jesus' prayer is a pattern, not a command! He says pray in "this manner", not in these words!
I am alive in Christ! I know because His Spirit lives in me and ALL those that know Him. Mere rote praying only fills the days... but God tells us to go into our closets! Your rosary beads are just decorations to distract you from God. Your "meditations" are merely a result of your indoctrinations through your early teachings. How often do you meditate on Jesus' Words? How about Paul. Try reading the Book of Romans. He spoke directly to your proud brethren. The muslims teach bombs and jihad to their young. Neither approach God's throne...!
You can find all of my points in Scripture. I won't bother to quote them here. Look them up yourselves. The same cannot be said for your organizations ritualistic requirements... which rarely have any Scriptural basis, but are born in the minds of your captors, the Roman hierarchy!
