The light and the night.

If you lose a loved one, cry
and when a child is born, jump for joy!
If someone leaves your side, fire him
and if he comes back, receive it with joy.
When it rains, get wet.

When the day shines, burn.
The sun is defeated at night
and she herself gives way to the new day.
IF peace flees from your soul,
wait ... it will come.

It's that simple
What light, if it is night?
