We do not have any attainment in the world of Infinity because all our attainment is possible only in the place that has an end. The sensation comes only at the border where everything ends. Therefore, in the state of infinity, we cannot perceive or understand anything.
It is as if I were thrown into the open cosmos and there is nothing but darkness, not a single ray of light, and it is not clear where the top, bottom, right, or left are. I do not understand anything, I am spinning in zero gravity and I do not feel where I am or what is happening to me. This is called the world of infinity.
The central point in the world of infinity is the point where everything ends: both desire and light. It is like a black hole.
