Kahlil Gibran, The Tides of Breath

You are not enclosed within your bodies,
nor confined to houses or fields.
That which is you dwells above the mountain
and roves with the wind.

It is not a thing that crawls into the sun for warmth
or digs holes into darkness for safety.
But a thing free, 
a spirit that envelopes the Earth
and moves in the ether...
This would I have you remember
in remembering me.

That which seems most feeble
and bewildered in you
is the strongest and most determined.

Is it not your breath that has erected and hardened
the structure of your bones?
And is it not a dream
which none of you remember having dreamt,
that builded your city and fashioned 
all there is in it?

Could you but see the tides of breath
you would cease to see all else,
and if you could hear the whispering of the dream
you would hear no other sound.

- Kahlil Gibran, The Prophet
