The defenition of mental concentration is perhaps focussing someone’s thinking on a particular subject without distraction. A normal sensable man’s mind always distracted in different thoughts. It is like throwing a basketful of marbles from a hill top on to a hard floor and through concentration we are to collect those widly scattered marble like thoughts into a basket.
