If the nature is so indifferent, then from where do we get any kindness and love?
From the evolutionary nature's first derivative: our mothers.
Our mother is both kind and harsh to us; harsh if we make mistakes, and to teach us the discipline;
even if you are very old, and even a grandparent, she would pay the same attention to you:
beta did you eat?
do not do hard work, you have done a lot,
take care of your own health, and so on...
I heard the above words from my 98 year old mother, when I recently spent three days with her in Jamnagar, where she stays with my second younger brother; I am 76+!
That is the mother.
A mother is only unique creature in this known universe that is full of attention, care, affection, and kindness; and all that put together is love.
