The name of God has gone through much change since it was first recorded in the days of Moses. Rabbis will tell you it is pronounced Yahweh, but the early Hebrews changed the scripture to read Adonai, or Lord, out of reverence for the name. It has since been translated as Yahovah, or Jehovah for us English speaking folk.
I have learned through my experience that all of these are the incorrect voicing of the name of God. The first time I heard it was when Abraham was freed from his bands by the exalted being just before he was to be sacrificed by the Priest of Elkinah. Abram called out, “Who art thou?” and the Lord spoke His name directly. When I heard it my heart felt that it would melt away and it shook me to my bones. It was a singularly unique experience of anything I have witnessed in the Heavenly Realm.
The word has no consonants, and begins with a breath in, and then an exhale while resonating the Word. It is the Word of Creation used by the Gods when they call forth the Children of Light, and as Father and Mother organize the creation of worlds without number. It is who He is, the Great I Am, for He exists and creates because He is able. In the Heavenly realm I never speak it, but address Him as Lord or Father.
