It is a well known fact that when we sleep, our body relaxes completely and our conscious mind is at abeyance. However, our subconscious mind is always awake. It never takes a day off.
As the conscious mind is out of the way, the subconscious mind can be approached directly. If instructed properly, it can play wonders with our life. Thus, slumber, instead of being just resting and recuperating, can also become creative and constructive.
Ensure that you get adequate amount of deep, undisturbed sleep. It is not my purpose here to discuss how to be good at it. If you have difficulty with it, please get help from your doctor to overcome the problem.
In the following links I have discussed only a limited number of benefits. Please remember that a variety of problems can be solved using this method. To list just a few: developing an excellent memory, developing self esteem, staying energetic throughout the day, overcoming timidity, developing concentration, developing good study habits (especially for children), etc.
