Katha Upanishad 11.2.2

 The self is the sun shining in the sky,

The wind blowing in space; we are the fire 

At the altar and in the home the guest;

We dwell as human beings, in gods, in truth,

And in the vast firmament; we are the fish

Born in water, the plant growing in the earth, 

The river flowing down from the mountain, 

We are incomparable.
