A small rent in a piece of cloth can quite easily be mended if it is attended to at the time when it is small. But if the proper moment is allowed to pass away by thinking that the rent is an insignificant thing, its mending will call for a good deal of labour. Again, the rent may become bigger and bigger with the passage of time and eventually go beyond the scope of repair, with the result that the piece of cloth turns out unfit for use. Such is the case with all evils. All evils can be easily removed by a little timely care. But if they are allowed to take their own course, they will get harder and harder to cope with and may even lead to total damage. Thus, one cannot do better than attending to a problem just when it begins to develop.
