I'm reading "My Stroke of Insight" by Jill Bolte Taylor and was excited to find she had this to say:
"We are designed to focus in on whatever we are looking for. If I seek red in the world then I will find it everywhere. Perhaps just a little in the beginning, but the longer I stay focused on looking for red, then before you know it, I will see red everywhere."
This has been my experience of the world, and is most obvious to me as a result of the Photo Art Journals that I host every couple of weeks. The photo theme makes sure that I keep my eyes open for images that speak to the theme. Recently the themes have been the colors. A book each for Red, Blue, Green, Yellow, Orange and Purple. You can find what you are looking for everywhere once your unconscious starts being on the lookout on your behalf (just remember to carry your camera with you!).
I imagine that this applies to everything in life. What you focus on expands.
Neale Donald Walsch says it this way: "Whatever you are being, you are creating."
So here is some of the red I've found in the world!
