Turning the page

I turned the page in my day calendar today and found the following Buddhist poem. Odd how when you need some guidance it has an unexpected way of finding you.

Everything is changing
It arises and passes away.
The one who realizes this is freed from sorrow.
This is the shining path.

To exist is to know suffereing.
Realize this and be freed from suffering.
This is the radiant path.

There is no separate self to suffer.
The one who understands this is free.
This is the path of clarity.
