This is the Kanizsa triangle.
No doubt you can see a white triangle and three black dots in the image.
Our minds fill in the blanks to create these.
Yet the truth is, there is no complete shapes in this image.
Our mind’s imagination provides what we want to see by filling in the lines.
In a similar way, our perceptions and beliefs from the past can cause us to see certain things, even if only true in our minds.
Becoming clear of these and re-programming can be useful so that the perceptions and expectations don’t hold us back.
