The guru answered: You say that nothing you will do matters. But your vision is two-fold flawed. Never doubt that you must be good, for if all good men were to think thus, the world would have only evil. And why do you so privilege your children's children? If you have done well for your people now, is not their happiness as meaningful as your children's children's happiness? Though you may be ungrateful for the deeds of your father's father, I am sure my father's father was appreciative in his time. It is given for a man to make right what he can, not to make right what he cannot.
And so the guru concluded: Do not seek to please your descendants and your contemporaries both, for in so seeking, you will please neither.
