Thank you for your advice and book recommendation. For the time being, I have decided to continue working through Al Brooks's book. I am about half-way done now. I found that it became easier to understand his book after getting through the first three chapters. At this point, I can usually understand the literal meaning of what he is saying and follow his comments on the illustrations. I cannot say I have grasped the deeper mysteries of Al Brooks's thoughts yet. I am hoping that those mysteries will become clear to me after the second review.
