Someone you trust hands you a photo of a man. They tell you it’s the picture of a saint who spent his life helping others in need.
Notice how the mind immediately begins to see that person in the photo as a saint, a good person.
Now, the person showing you the photo says they gave you the wrong photo and that the photo you are looking at is a notorious thief who spent his life stealing and harming people.
Notice how the same face you are looking at now begins to look like a thief. To you, the very same person in the photo appeared as both a saint and then a thief.
What does this example tell us about perception?
The world is what we see it as. What we choose to see it as. And beyond that would we even be able to perceive in another something that is not part of ourselves already in some way?
