How can we pray effectively?
To pray most effectively, your prayer should be outwardly inaudible, but you may form a sentence of a few words that will convince your aspiring mind. The heart is already aspiring, but the mind needs to aspire. So it is better for the prayer to take the form of words.
You may form the sentence by writing it on the tablet of your heart. Then try to see it there. Once the words are written, you can return many times to see them. If you want to repeat the sentence, good, but it is not necessary. When you repeat your prayer you have a choice. Either write it once on the tablet of your heart and read it again and again, or continuously write the same thing-whichever gives you more joy.
