Prayers can be used as the basis for meditation practices. Obviously there are many different prayers. Let us examine one as a pattern for others.
The Lord's Prayer in English can be translated as: Our Father/ Who art in Heaven / Hallowed be Thy Name / Thy kingdom come / Thy Will be done in earth as it is in heaven / Give us this day our needs / dismiss our debts as we dismiss the debts of others / lead us not into temptation/ but deliver us from self-consciousness / for Thine is the Kingdom and the Power and the Glory for ever. Amin.
In Aramaic it isa: Aboon / d'baahmaya / Nitkaddash shm(u)och / Teete malkootach / Nehve zviyanuch ayekana d'bashmaya off b'ar'ah / Havlan lachma d'soonkannan yaoomana / washbooklan chowvine wachtahine ayekana doff chinnan shvokin l'chaiyovine / wela tahlan linisyuna / ela patssan mem bisha / metool d'loch he malkoota wachaila weteshbookta l'olam aleem. Amin.
One approch to this prayer is to break it into phrases (as above), say the entire prayer, repeat one phrase, and then meditate upon that phrase. Each day the phrase differs. Go from the beginning to the end of the prayer.
A more detailed practice could be as follows: 1. break the prayer into phrases. 2. Sit quietly and follow the breath, letting all thoughts go. Let yourself feel the breath coming through all the pores of your body. Become the breath. 3. Repeat the entire prayer in Aramaic ten times. 4. Relax and breathe in the prayer. 5. Take the phrase you are working with and repeat it aloud 100 times in Aramaic. 6. Sit quietly in meditation upon that phrase: its meaning, its reality, becoming it. 7. Repeat the phrase 100 times again and then the prayer ten more times.
After ten days you will have finished the entire prayer. After that, spend twenty minutes in meditation (instead of ten) upon each phrase. Repeat the cycle in this way. Then repeat the cycle four more times, increasing the length of meditation time to one hour upon each phrase. This will take sixty days. Then for the next six days simply repeat the prayer ten times , absorb it and be absorbed by it. Become it. The completed exercise takes sixty-six days.
All prayers may be divided into phrases and each aspect used as a focus. The exact pattern of the practice may differ depending on the individual and the circumstances. Unless you are instructed to do it in a certain way, let your intuition lead you. A word of caution: you get what you pray for.
