Reality?
What’s your first impression when you look at this picture? Was it a woman with black hair or a saxophone player with a big nose? If you only saw one and not the other, is it easier now that you know that there are two alternate images?
You can also take a look at the spinning dancer shown in this link: https://youtu.be/8J0o8c7-PiE . Some see her spinning from left to right on her left foot, others from right to left on her right foot.
“So we fix our eyes not on what is seen, but on what is unseen. For what is seen is temporary but what is unseen is eternal.” 2 Corinthians 4:18
As there are two realities in the optical illusions, there are two realities coexisting in this world: the material and the spiritual. If we don’t open our minds to the possibility that there is a spiritual world also present within the fabric of the material world, we may never see it. But if we tell our minds that there is another reality present, then this faith in God’s unseen world will make us much more likely to see its reality- a coexistence of the miraculous.
