Zeta Seal
The Zeta Seal is located in the Astral Plane layers of the heart complex to block activation of the 4th DNA strand which blocks access to the Mentor Fields (first layer of the higher self mind) in the 5th dimension. Essentially it is the 4D frequency fence placed in the human body to keep the human soul reincarnating in the Astral Plane under the control of the NAA during the death process. It creates a multitude of blockages that separate the heart sensory abilities from being recognized by the mental body or conscious mind.
