Of the four methods I have been using to read the Coelbren, this is the simplest.
Write down your question. Be still and calm until the question is clear in your mind. Shake the bag in which you keep your Coelbren. Draw out one tile. Note it down under the question. Look up the meaning of the tile, and contemplate its application to your question.
Note the sound of the letter you have drawn, and say it out loud, both as a single syllable, and then drawn out. Does the sound add anything to your understanding of the answer? Consider the shape of your mouth as you make the sound, and how it feels. Where is the sound creating sensations in your body? Does this add to your understanding?
Obviously, this is not going to give complex answers, but it’s a good method for a quick, simple insight.
