Your subconscious mind is the seat of your emotions and is the creative mind. If you think good, good will follow; if you think evil, evil will follow. This is the way your mind works.
The main point to remember is once the subconscious mind accept the idea, it begins to execute. This law, when applied in a negative way, is the cause of failure, frustration and unhappiness. However, when your habitual thinking is harmonious and constructive, you experience perfect health, success and prosperity. Whatever you claim mentally and feel as true, your subconscious mind will accept and bring forth into your experience. The only thing necessary for you to do is to get your subconscious mind to accept your idea, and the law of your own subconscious mind will bring forth the health, peace or the position you desire. You give the command or decree, and your subconscious mind will faithfully reproduce the idea impressed upon it. The law of your mind is this: You will get a reaction or response from your subconscious mind according to the nature of the thought or idea you hold in your conscious mind.
There are two spheres of activity within your mind. Your conscious mind is the reasoning mind. You make all your decision with your conscious mind, for example choosing books, your home and your partner in life. On the other hand, without any conscious choice on your part, your heart is kept functioning automatically and the process of digestion, circulation and breathing are carried on by your subconscious mind through processes independent of your conscious control.
Your subconscious mind accepts what is impresses upon it or what you consciously believe. It does not reason things out like your conscious mind, and it does not argue with you controversially.
Remember, your subconscious mind does not engage in proving whether your thoughts are good or bad, true or false, but it responds according to the nature of your thoughts or suggestions. Hence, it is very important to select thoughts, ideas and premises which bless, heal, inspire and fill your soul with joy.
