It is a retarding element creating hatred and anger, and causing people to fight each other, and making them unsympathetic.
Swami VivekanandaThose who grumble at the little thing that has fallen to their lot to do will grumble at everything. Always grumbling, they will lead a miserable life, and everything will be a failure. But those who do their duties as they go, putting their shoulders to the wheel, will see the light, and higher duties will fall to their share.
Swami VivekanandaThis caste system had grown by the practice of the son always following the business of the father.
