The main thing is to nullify every one of your personality traits. You must strive to do so until you have totally obliterated your ego, rendering it into absolute nothingness before G-d.
Begin with one trait and annihilate it completely. Then work on your other traits, one at a time, until they are totally nonexistent.
As you annihilate your ego, G-d’s glory will begin to shine through and be revealed.
It is written, “And the earth was alight with His glory” (Ezekiel 43:2). G-d’s glory is like light.
