Mer-Ka-Ba comes from Maat, which means more than to ascend. It was the 'primal' or a pattern of the stages in spiritual evolutionary development.
The Merkavah is the vehicle of ascension. In the Zulu thought, Merkaba is the vehicle that transports one through space, time and dimensions. The Hebrew meanings are, 'Chariot' and Throne of G-D'. The Ancients of Africa in Egypt or Maat, Merkavah was actually three words.
"Mer" means Light of energy that revolves or turns within itself. "Ka" means spirit of humans. "Ba" means the human body or the concept of reality the spirit holds within the body. Technically speaking Mer-Ka-Ba is an electro-magnetic field. I am thinking that the Mer-Ka-Ba is closely related to, if not all, a part of the Schumann Resonance.
