So, I'm kind of new to the forum and all that, but was wondering if anyone every noticed something kind of interesting.

In FMA, one of the main philosophies of Izumi Curtis is "One is All, All is One." So thinking about this yesterday, I flipped on some Led Zeppelin and started listening to Stairway to Heaven. And then the final lyric of the song struck me:

And as we wind on down the road
Our shadows taller than our soul.
There walks a lady we all know
Who shines white light and wants to show
How everything still turns to gold.
And if you listen very hard
The tune will come to you at last.
When all are one and one is all
To be a rock and not to roll.

I just thought it was kind of interesting....

Anyways, as a question, I was just wondering if anyone knows where the quote "All is One, One is All" might have originated? Thanks.
