If you can fill your time
So that it’s full with only now
And not the past or future
If you can fill your mind
With boundless space
And not any other feature
If you can fill your heart
With only love
And leave no room for hate
If you can find your soul
In heaven and this earth below
Whole in one
You are my teacher!
