ahh help with a quote..

[GelidStar]

i am stuck, i came across a specific line a book (yeah i can't remember which book) but maybe someone has heard this statement similar...

that which is already is.  nothing cannot be which already is, since is exists then what is not actually is...

it goes on and on like similar to Gary Zukav's quote...

"Reality is what we take to be true. What we take to be true is what we believe. What we believe is based upon our perceptions. What we perceive depends upon what we look for. What we look for depends upon what we think. What we think depends upon what we perceive. What we perceive determines what we believe. What we believe determines what we take to be true. what we take to be true is our reality."

It could of either been from Robert Monroe's Ultimate Journey, Robert Bruce's Astral Dynamics, Samuel Avery's Dimensional Structure of Consciousness, Bruce Goldberg's Astral Voyage or actually by Zukav himself.  I have been looking and looking and can't find it.  Anyone know?
