Reality is what is taken to be true.

Reality is what we take to be true. 
 

What we take to be true is what we believe.
What we believe is based on our perceptions. 
What we perceive depends on what we look for. 
What we look for depends on what we think. 

What we think depends on what we perceive. 
What we perceive determines what we believe. 
What we believe is what we take to be true. 
What we take to be true is our reality.

— David Bohm, theoretical physicists

Pretty straight forward if you ask me!
