Sofia and Time; dedicated to "Sofia", Bulgaria 2016
 

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 on what we think,   What we think depends on 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.
