There is lot to be said about how one speaks the words of ritual. Some words, particularly those in languages other than your native tongue, should be spoken in a special manner—in a slow, sonorous, or deep and resonating voice. Think of the deep sounds emitted from a church pipe organ!
You should feel stimulated as you intone these words so, as Louis Culling wrote, that you have "goose-pimples running up and down the spine." He also suggests that one should imagine "that the magickal power of the words derives from the many magicians of centuries past who have used these same words."
Others have suggested using your imagination to see the words projected out into the universe, awakening whatever it is you are calling. In the case of the barbarous words for the five elements, you want to sense that you are awakening these powers to respond to your call, and that you are being filled with them.
These words you speak in your Individual Rituals are for you, alone. You are not performing before an audience, not even an invisible one! This is important—it is easy to get carried away by your own voice, resulting in an inflated ego, which is the antithesis of what you need.
The inflated ego of the magician, the religious preacher, the politician, or anyone speaking or reading aloud, can create a barrier separating you from your Higher Self and decreasing your psychic and occult abilities even to the point that you will be misled by them.
