I'm confused...

So, it is really nice this week after feeling like early winter last week...hmm. I know that this time is usually called "Indian Summer," but why? What is the meaning behind the name?

Is this correct?

Prayer of Abandonment

My Lord God,
I have no idea where I am going.
I do not see the road ahead of me.
I cannot know for certain
where it will end.

Nor do I really know myself,
and that I think I am following your will
does not mean I am actually doing so.

But I believe
the desire to please you
does in fact please you.
And I hope I have that desire
in all I am doing.

I hope
I will never do anything
apart from that desire.
And I know if I do this
you will lead me by the right road
though I may know nothing about it.

I will trust you always
though I may seem to be lost
and in the shadow of death.

I will not fear,
for you will never leave me
to face my perils alone.
