Keep the Mind in a Definite Thought Channel.
Now, after a few minutes of this practice, take another sheet of paper and write on it:
“I can dig up any fact in my mind.”
Again relax and close your eyes, and then study these words. If your mind is going to dig facts out of your memory, it must not have other things to do at the same time.
Try to dig up the name of somebody you have forgotten, or something you have read.
Now, as you proceed from day to day, get relaxed and take some book or paper and read some useful thing. Try to shut out every other thought, so that your mind can wade into the facts.
Then sit back in your chair, with your eyes closed, and analyze what you have read. Ask yourself questions about it. The more interesting the subject, the more readily you will go into it.
After a few weeks you will begin to look into things more carefully, and make your mind impressions deep.
Get into the habit of concentrating on what people tell you, on what you read, or see, or hear.
Then you will soon learn how to shut out everything that does not pertain to the subject, and you will make your impressions stronger. Also, you will begin to bring out truths that you have almost forgotten.
