In English
There is a small example for this. If a son is born in a family, there is considerable happiness; but the death of the same son will cause untold sorrow and grief. It is the same son that is either born or is dead, and the change of the act of birth to an act of death changes the happiness to sorrow. Without sacrificing, man cannot live; but he does not undertake sacrifice knowingly. Every individual does undertake sacrifice, but he does not know that he is sacrificing. One should have sacrifice as his aim, and one should enquire into what is permanent and what is not permanent and enquire into what is to be given up and what is to be accepted.
