Is Hope a Coil of Metal

Is hope a coil of metal,
Kinetic energy held at bay?
Is that coil still eternal
Once flat – its energy gone away?
Or is hope a fall of water,
Rushing from a hole in the ground?
Could it be if the rushing can stop
And no water can be found?
Or is hope a little seed
That sprouts to grow some more?
Until that cycle of seasons breaks –
Spring eternal rather than four.
