The mental processes are not limited to the field of consciousness alone. The field of subconscious mentation is of a much greater extent than that of conscious mentation. Messages when ready, come out like a flash from the subconscious mind to the surface of the conscious mind, through the trap-door in the subconscious mind. Only ten per cent of the mental activities come into the field of consciousness. At least ninety per cent of our mental life is subconscious.
We sit and try to solve a problem. We fail. We look around. We try again and again but we fail. Suddenly the idea dawns that leads to the solution of the problem. The subconscious processes were at work. The subconscious mind is your constant companion and sincere friend. Even in sleep it works without rest. It arranges, classifies, compares, sorts the facts and figures and works out a satisfactory solution.
With the help of your subconscious mind you can change your vicious nature. By cultivating healthy, virtuous qualities you can overcome the vicious nature. If you want to overcome fear, mentally deny that you have fear. Concentrate your attention on the opposite quality, the ideal of courage. When courage is developed, fear vanishes by itself. Positive overpowers negative. You can establish new habits, new ideas, new tastes and new character in the subconscious mind, just by changing the old ones.

All actions, enjoyment and experiences leave their impressions in the subconscious mind, in the form of subtle impressions or residual potencies. Samskaras are the root cause for life and experience of pleasure and pain. Revival of samskaras induces memory. The yogi dives deep inside and comes in direct contact with these samskaras. He directly perceives them through inner yogic vision. When you desire to remember something you have to exert. You have to go down to the depths of the subconsciousness and then pick up the right thing from a curious mixture of multifarious, irrelevant matter.
