WHAT DOES IT MEAN?
If you want to break free from ignorance you need to understand Troward´s paragraph. It can set you free from possible limitations you hold in your mind. Let´s look at the paragraph step by step.
First of all he says: "my mind is A center... " - not THE center. A center.
My Mind is A center, Your mind is A center, everybody's mind is A center. How can that be?
Since we are dealing with infinity there are no boundaries. We are used to boundaries (width, height, length) and we can easily figure out the exact center of something - for example a room.
We just measure it and we can calculate the exact center. And there is only one center to a room, not many.
But, when we are dealing with infinity there are more than one center. There are infinite centers. We are all centers - your mind is, my mind is everybody´s mind is.
We are all part of The One, The All, The Everything and The One is infinite.
