Analysis of I am

I am the breeze that gently blows
to swell the sails of your boat.
I am the wind that rises at dawn
to guide birds' flight o'er land and shore.
I am the hill whereon you climb
to safely reach your home.
I am the wave in constant flow,
in high tide and in low.
In leaps, swift and graceful,
I am the legs of the gazelle and fawn.
When in the desert, fearful you roam,
 my  arms I bear you on.
