Concentration always throws light and gives one greater clarity.Even scientists know that they have to concentrate on a problem before they can solve it.
Most of the time, the solution to any problem a person is trying to solve is already within him. It is present in the subconscious level but the solution will not become evident unless his mind is in a focused condition.
THE MOMENT THE MIND IS FOCUSED, THE ANSWERS FALL INTO PLACE!!
From my own experience, many questions that I have focused on have found their own answers.
Somehow, somewhere, almost inevitably, THE ANSWERS COME!!
