You don't really understand. This prayer (the Jesus Prayer) that I showed you has been practiced by the Christians since the 2nd century. The earliest form was just a simple naming of Jesus on their lips. Read the story of St Ignatius the God-Bearer, and you will see a clear example of this. "This holy man is called ``the God-bearer'' because he constantly bore the name of the Living God in his heart and on his lips. "

St. Paul said, "The teaching which accords with godliness", that is simply what I was saying. This is a Christian teaching which accords perfectly with godliness, it is a part of holy Christian tradition (2 Thess 2:15).
If it is a "vain repetition" as you claim, then the Lord's Prayer is a vain repetition, as well as the blind beggar who repeatedly cried to Jesus, “Son of David, have mercy on me!” (Luke 18:38), and the Publican who could not so much as lift up his eyes to heaven, but smote upon his breast saying, "God be merciful to me a sinner!" (Luke 18:13).
Not only do these verses support repetitive prayer, they also support the use of the Jesus Prayer.
When Jesus spoke about prayer, he did not condemn repetitions but vain repetitions. He meant us not to say the repeated prayers without any real meaning or purpose, to babble like a pagan idolater. He was not at all condemning repeated prayer, only prayer that is futile - empty, vain, and without any spiritual fruits.
You are mistaken on the meaning of Christ's words.
"Let everyone that nameth the name of Christ depart from iniquity" (2 Timothy 2:19). Another clue to the use of the Jesus Prayer. The name of Jesus is sharper than any 2 edged sword.
>>Again Lord Jesus said; "Mat 6:7 But when ye pray, use not vain repetitions, as the heathen do: for they think that they shall be heard for their much speaking. "
Your example and reasoning is more in your own philosophical way and understanding. If we examine the scriptures, Lord Jesus is telling us that He knows what is in our hearts and we do not need to keep repeating a words just to be heard of. Your example like the way Lord Jesus told us on how pray; that is not a "vain repetitions". What Lord Jesus wanted us to know is the aim of the pray and not necessarily pray the same words as given. But we have to model our pray as He teaches us. Same as the beggar as shouted Christ Jesus name. The beggar is only persistent to call the Lord without reservation. This beggar has shown us on how to persevere as we know he is so desperately in need of God's attention because the Lord Jesus Christ is present at that time. Praying to God right now is different from such situation. "Mat 6:9 After this manner therefore pray ye: Our Father which art in heaven, Hallowed be thy name. " Now did you copy the word "after this manner" Lord Jesus Christ did say that we pray these verses. But what He wanted us to pattern or model our prayer which means.
1. We have to give glory to God acknowledging He alone owns all the glory "Which art in heaven...Holy be Thy Name".. Praising God
2. We have to acknowledged that He is an Almighty God "Your Kingdom come..Your ..." Submission
3. We have ask His grace and mercies and admit He owns everything ."Give us this day.." petition
4. We have to ask forgiveness for our short coming " And forgive us..." to humble ourselves
5. We have to ask protection, guidance and comfort " And lead us not...Deliverance
Now tell me that Lord Jesus Christ Teaching is consider as an example of vain repetitions? As you're just claimed..
