The mind is like a piece of paper that has been folded. Ever after words it has a tendency to fold in the same crease, unless we make a new crease or fold, it will follow the last lines. The creases are habits every time we make one it is so much easier for the mind to fold along the same crease afterwards. Let us make our mental creases in the right direction.
Here the creases mean habits. If you make your mind train with good habits it will automatically support you at the time of need. Always take guard against creating a bad habit as it is recorded into your subconscious mind and your subconscious mind Works automatically as per its records. Your subconscious mind is a storehouse and it works according to the habits stored in it. So never store bad habits into your subconscious mind. It is just like a nervous system which works automatically as per requirement.
So always create and store good habits and eliminate and resist bad habits because what you are is a reflection of your habits stored in you.
