"The Christ is said to have warned his disciples not to use vain repetitions when they prayed, as did the heathen; and from that text the deduction has been made that all repetitions are useless. They assuredly would be so in an invocation addressed to the Deity, for they would imply that he had not heard the first request! They would be (or should be) unnecessary for disciples—for men who have already made some progress along the path of development; to formulate an [intention]] clearly and to express it once strongly should surely be sufficient for them. But the ordinary man of the world has by no means reached that stage; it often needs a long course of steady hammering to impress a new vibration upon him, and so for him repetition are far from useless, for they are deliberately intended to produce definite results. The constant impinging of these sounds (and of the various undulations which they set up) upon the different vehicles does tend steadily to bring those vehicles into harmony with a particular set of ideas. p. 147"
