What is known as the water method is, although very simple, very effective in inducing sleep.
Put a full glass of clear water on a table in your sleeping room.
Sit in a chair beside the table and gaze into the glass of water and think how calm it is. Then picture yourself , getting into just as calm a state. In a short time you will find the nerves becoming quiet and you will be able to go to sleep. Sometimes it is good to picture yourself becoming drowsy to induce sleep, and, again, the most persistent insomnia has been overcome by one thinking of himself as some inanimate object-for instance, a hollow log in the depths of the cool, quiet forest.
Those who are troubled with insomnia will find these sleep exercises that quiet the nerves very effective. Just keep the idea in your mind that there is no difficulty in going to sleep; banish all fear of insomnia. Practice these exercises and you will sleep.
By this time you should have awakened to the possibilities of concentration and have become aware of the important part it plays in your life.
