If we go back in our history, also can be seen in the present, we see that most of thoughts are repeated in our routine life. Psychologists have estimated that on an average we have as many as 60,000 thoughts per day more importantly; 95-98% of those 60,000 thoughts are repeated daily. Even our religious expert also suggest for repetition theory; like mantra, certain prayers or rituals. The certain things activate the specific part of brain cells. But when mind become used to from certain things, then they start frustrated. In today’s fast mental world this theory doesn’t suit.
In my personal experience in meditation, I prefer this repetitive theory for children or beginners only. In long run it makes mind very dull. If you see around your filmi friends, they have an established mental pattern where their mind works. Like Ram gopal verma one of the biggest film director in Indian film industry, he has a certain thing of repetitive mental setup which can be seen in his every movie. In the future his mind will have no creation because repetitive ideas come. In repetition, the receptivity of mind becomes dull. New ideas cannot come.
