Help me trace the source of this quote by Nikola Tesla.

Sorry if this is in the wrong forum, I tried posting this in the research forum but it said I was not permitted to do so.
I have seen this quote of his many times:

"The gift of mental power comes from God, Divine Being, and if we concentrate our minds on that truth, we become in tune with this great power."

I go here and it says that its from an article written by Tesla called My Inventions.
en.wikiquote.org...

The I click on the My Inventions link at the top and the webpage it takes me to does not even have that chapter in it.
www.tfcbooks.com...

But there is also other webpages that have the 'same' article that says different things.
www.lucidcafe.com...

But this says different.
en.wikipedia.org...:_The_Autobiography_of_Ni kola_Tesla

So basically without wasting your time, and I am sure you can see why this is confusing to me, are these two separate articles with the same name? Or, is there a hoax going on here or what? I am probably missing something very obvious, I am just curious if Tesla really did attribute his knowledge to God.

It's from his Autobiography - Chapter 5 Paragraph 6

I would trust that. You have the link there already I see - seems legit.
