Where do we perceive? What is around me, and who am I? Can I exit from inside me and look at myself and all other people from outside? Can I change my sense organs: take out an eye, ear, etc, change something? Yes or no? Who am I and what is the world surrounding me?
From outside, there is only one, single, infinite even Light, and we exist in it.
I do not feel that Surrounding Light. I do not perceive it. I feel the difference between the Light and me. My task is to come the point when the Light and I are in the state of complete balance, meaning complete similarity. Coming closer to this similarity means to ascend by the spiritual degrees.
