Change is the Principle of the world.

परिवर्तन ही संसार का नियम है। 

Whatever has happened that was good, whatever is happening that is good, What is going to be that also will be for good. What you lost for which you are crying? What you brought, which you lost. What you did, that is destroyed. Whatever you have, it’s from here only you took. Whatever you gave you took it from here only. Whatever is yours today will become for someone else, tomorrow, and some others day after tomorrow.
