What is life?

What is life?
We are here to perform our duties and complete our responsibilities which cannot be done by someone else.
but how do we come to know ourselves? How can one find out oneself?
How much do u exactly know about yourself?

You or Me identify with our body,mind,soul and all our things we have bought with money or with birth.
But are they really ours?
How much time do u intend to stay?
What you plan to get from life?
