Dear Pramila, upper caste children will surely clean toilets. Even in your own scriptures it is mentioned that "IN KALYUG CHANDALA WILL RULE OVER BRAHMINS". If you have not read it yet, please go and read it. It will help you cope. After your kids clean toilets diligently for several lifetimes, they can hope to be reborn as DALITS who will enjoy RESERVATION. This is your KARMA, your DESTINY!!! It simply cannot be changed at all because it is written in your own Shaastras by BRAHMINS themselves!!! HOWZZAT?
