Tap the Subconscious Mind

With the help of the subconscious mind you can change your vicious nature by cultivating healthy, virtuous qualities that are opposed to the undesirable ones. If you want to overcome fear mentally, deny that you have fear and concentrate your attention upon the opposite quality, the ideal of courage. When this is developed fear vanishes away by itself. The positive always overpowers the negative. This is an infallible law of nature. This is the Pratipaksha Bhavana of the Raja Yogins. You can acquire a liking for distasteful tasks and duties by cultivating a desire and taste for them. You can establish new habits, new ideals, new ideas and new tastes.

If an idea is planted in the mind, it grows at night through the operation ofthe subconscious mind. The subconscious mind never takes rest. It works vigorously throughout the twenty-four hours. Those who know how to manipulate this subconscious mind can turn out tremendous mental work. All geniuses have control over the subconscious mind. You must understand the ways of extracting work from the subconscious mind. Subconscious mind is a wonderful underground mental factory.
