Some say that the Tetragammaton mantra reveals the inner essence of God. Through the vibration of this mantra Fohat works on programming and reprogramming rods of DNA and RNA according to the 72 qualities of the Divine Spirit. The Divine name is the 4-fold name of God expressed through the 4 elements of fire, water, air, and earth . We pronunce the name Yod Hey Vau Hey. In Transmission we will seal the room with the Hebrew Father letters.
Hey h Vau v Hey h,Yod I
This seals the room from negativity in six directions, up, down, forward (east), back (west) ,right side (south), left side (north).
Close your eyes. Sit in your chair with feet flat on the ground. Now begin by doing some deep rhythmic breathing
Imagine looking upward but keep your eyes closed.
Above: Look above your head and seal this space with the letters
Below: Look below and seal the space below you with the letters
Hey h Vau v Hey hYod I
Forward: Look at forward and seal the space with the letters
Backward: Look behind you and seal the space with the letters
