Yesterday I was yesterday.
Tomorrow I will be tomorrow.
Today, I am today.

I am always today.
Even yesterday.
Even tomorrow.

If I try to be tomorrow today, suffering.
If I try to be yesterday today, suffering.

If I am today tomorrow, peace.
If I was today yesterday, peace.

I am not a constant. I am change.
I cannot resist what I am.
If I try.. suffering.
But I am also a constant.
Always I am what I am.
How can I be permanence and change at once?

Like this.

Tat Tvam Asi.
