What if our other perceptions were like that too? What if you think something is one way but in fact, it might not be at all? Maybe you can use this to your advantage.
What I'm trying to get to is a sort of "fake it 'til you make it" kind of thinking, or perhaps "reframing". If you can bring yourself more peace and well being on the inside by allowing yourself to know that perhaps there is a "benefit of the doubt" to a situation that is causing you mental or emotional anguish. Perhaps you can even imagine your way out of mental or emotional pain.
Can you think of ways you can use this idea to give yourself the gift of freedom? What you thought was dark grey was really light grey visually, so maybe what you thought was not so nice, could really turn out to have a big benefit for you?
What are the ways you can think of to use this idea to make some area of your life happier?
