In English
It is natural even for a strong block of iron to acquire rust while it is buried in dust. The block of iron when rusted loses its shine and strength. The same block of iron shines with splendour when it is cast into fire. After undergoing severe treatment in fire, a piece of iron becomes bright, soft and strong. Similarly man’s duty lies in self-transformation. By such sincere self-transformation, man can transform even black into white.
