Now that I am channelling Alpha frequently, I have become convinced that he adjusts the way in which he presents himself according to the audience or client. Sometimes he swoops in unexpectedly with an almost stupefying intensity and gives advice word by word. At other times he hovers in the background without causing any physical sensations and I am not entirely sure he is there until I hear him calling out individual words, to direct my attention to particular topics he would like me to raise. Then there are times when he likes to do a double act with me - feeding me a few sentences, then asking me to explain an idea in my own words, and then taking over again. At other times he feeds me a long string of ideas, giving me time to explain each idea in my own words.
His formula seems to be a combination of how physically intrusive he wants to be (when he gives me a strong trance dictation, he causes physical symptoms in me and often in the listener too), the complexity of the ideas he wants to convey, and how much he wants me to be seen as an ordinary speaker rather than a medium. These days, my own health or vigour don't seem to have much to do with the mode he chooses. It seems that when you have a well-oiled channel, your guide can pick and choose how to present itself
