Gems of Congnition

I grew up in the San Francisco Bay Area and when I was 19 years old I came across this little book called Gems of Cognition.  It was written by a Hindu Yogi named Sri Subramuniya in 1958 and was published by Christian Yoga Publications in San Francisco.  The book consists of 108 excerpts and paraphrases from his book Cognizantability.  (I don't think that is an actual word!)  This book and a poster I often saw in Haight-Ashbury (when my friends and I drove up there to buy weed) kick-started my interest in Eastern philosophy and religion.  The poster was of an Indian Mystic named Meher Baba.  Here he is:

The poster said this under his photo:
I AM THE ANCIENT ONE
I was Rama.  I was Krishna.
I was this one.  I was that one.
And now I am Meher Baba.

He was an interesting guy.  Now, before you start criticizing me about being a naive stoned-out hippizoid in my youth please remember that...yes, I probably was just that.  I was young and in the era.  Unfortunately many of my age group have forgotten all about this era...to all our detriment.  Peace and Love.  Nothing wrong with that.

 Getting back to the little book though:  one of the excerpts said this:  "You are not your mind, because you can control you mind with your will."  I've been ruminating about this statement now for over 50 years and for many of those years attributed it wrongly to Meher Baba...haha.   Anyway, I know that you know that this statement is true.  Here's the kicker though:  If you are controlling your mind with your will what are you controlling your will with?  It seems there are three separate things going on here.  Here's what I've decided:  I don't know.  I can't resolve this concept.  Somewhere back in my past though I remember some guru saying that:  "All concepts are false."  So there's that.
