The mind can very easily think of worldly objects. It is its nature. Thoughts generally flow with ease towards objects. Mental energy will readily flow in that direction. The mental force can easily flow in the old grooves and avenues of mundane thoughts. It finds it extremely difficult to think of Supreme. The difficulty in weaning the mind from objects and fixing it on Supreme is the same as in making the river flow towards Mountain instead of its natural flow towards Sea. It is like rowing against the current of the River. Still, through strenuous efforts and dedication it must be trained to flow towards Supreme much against its will, if you want to free yourself from birth and death. There is no other go if you want to escape from worldly miseries and tribulations.
How to Overcome the Thoughts
Overcome the stains of thoughts or the cloud of thoughts through the power of discrimination and constant efforts and be drowned in the ocean of Supreme bliss with spiritual illumination. When you try to bury your shadow in the earth, it always comes out. Similarly, when you try to overcome the thoughts through, they will come out again and again. Withdraw the mind from the objects. Purify the mind and fix it on the Space of the heart (Infinite Supreme). The mind will be annihilated in course of time.
Do not for a moment contemplate upon the things of the universe. You need not exert yourself too much to rid yourself of this thoughts. With the checking of all thoughts, one’s mind will perish. Having firmly annihilated the external thoughts through the internal one and having destroyed the impure mind through the pure one, rest firmly in your Soul-Knowledge.
When you are firmly established in the idea that the world is unreal, through names and forms , thoughts will slowly vanish. Always remember Supreme Soul alone is real. World is unreal. Human Soul is identical with Supreme. You will gain immense strength and peace of mind.
The State of Thoughtlessness
With the extinction of the base thought, there is the extinction of Ignorance and its effect, mind. Thought is pain. Thoughtlessness is all bliss.
When your thoughts, which are now dispersed, shall be collected together and you will remain in a state of repose, then the eternally happy Soul will shine forth as the reflection of the sun is seen in a clear surface of water. Peace is not in money, woman or eating. When the mind becomes desire-less and thoughtless, Soul shines and sheds forth eternal bliss and peace. Why do you search in vain for happiness in objects outside? Search within for bliss in the subjective, True-Conscious-Blissful Eternal Soul.
