Between the conscious and the subconscious, there are two lines of direction:
On the one hand, the conscious can transmit "at will" information to the subconscious. On the other hand, the subconscious we return information when necessary or as we call it explicitly. Hence the importance of programming.
Why is it important to use his subconscious?
Just because its working capacity and quantity of knowledge far exceeds those of your conscious. In addition, your subconscious is the control tower of all automatic functions of your body and it stores all the perceptions of your five senses.
Limiting yourself to the voluntary use of your conscious and unintended use of your subconscious, you limit yourself in the desired outcomes for the success of your life. Using this method of "voluntary use" of the subconscious you program it to give you a particular result, it asks nothing better since responds to your requests.
If you feed your subconscious mind that ingredients confused, disparate and inconsistent, your life will look like a puzzle whose pieces are still scattered left and right without ever reach despite your best efforts. But if you provide regular and tenaciously hard data, profound and generating success, your life will take a very different aspect: the pieces will complement each other as if by magic and you finally understand how to direct you.
