Very few of you know this fact that as innocence we are in childhood as we will again be when we grow older. Life repeats itself after complete cycle. In old age we again move to the innocence so that we again will be taking birth so we have to give up all the cunning things and ego which we have accumulated in our life.
So as pure we came from the above will be going as much purity. Very few old people lose innocence otherwise all of them are innocence and can be very best companion to kids.
