This is an excellent quote by the ancient sage. It is important to bring your mind back from it's mental wanderings... & be aware of NOW!
"If you are depressed, you are living in the past...
If you are anxious, you are living in the future...
but if you are at peace, you are living in the present."
This moment is the only one that we ever really have.
If we are not in it completely, we are not fully experiencing life & the world around us.
