Reality and Perception

Many years ago, I thought the following model for my perception of this world.

I thought the material sphere was the physical world, and my perception of its essence was just a reflection of the light (knowledge) bonded within the sphere. Some people think of two worlds, the physical world, and the metaphysical world. We are part of the material and physical world. It is beyond my ability to perceive and understand any aspects of the spiritual world, the region beyond the physical world.

As a physicist and humanist, my perception or even thinking of a metaphysical world is hopelessly futile. A follower of religious faith, do believe that only a divine revelation can penetrate the boundary (mirror wall).

Zoroastrian, the oldest monotheistic religion, plus Judaism, Christianity, and Islam regard as the essence of their belief in the divine revelation.

Those who believe in a metaphysical world have faith in an unfathomable entity. I envy them. I am hopelessly entrapped within a physical world. Can I measure the essence of a metaphysical entity?
