What powers support this body

Then Bhargava approached the sage and asked:
"Master, what powers support this body?
Which of them are manifested in it?
And among them all, which is the greatest?"

The sage replied: "The powers are space, air, fire,
Water, earth, speech, mind, vision, and hearing.
All these boasted, 'We support this body.'
But prana, vital energy, supreme
Over them all, said, 'Don't deceive yourselves.
It is I, dividing myself fourfold,
Who hold this body together.'"

-Prashna Upanishad
