The river

 The river doesn't choose it's route

It doesn't choose it's destination

It cannot even choose the direction it which it flows

It's only goal is to keep flowing

And get to it's destination

Where in this case it is the source of life

But the journey to its destination isn't always easy

There are sometimes huge rocks blocking the way, tree roots and branches

And the water can scream and beg or try to make them move

But it soon realises going around them keeps the flow going

It keeps the peace

And now and then a waterfall comes and down is the only way to go

But down is still on course

Down is still part of the flow

So for the sake of it's journey

For the sake of peace

It finds a way around

It keeps the course 

It flows ahead
