Merkaba

"Please, tell me about the Merkaba. What is it and when did it appear?"
"The Merkaba did not appear out of nowhere. It is a symbol of rebirth and the genesis of life. Two in one, like yin and yang, like life and death. Conception and resurrection.

Balance. Three points, three vertices, as a symbol of the triune: Soul, body, mind.

Three great gods.
Soul — the progenitor of all that exists.
The primordial, original concept, the intent.
Mind. It is the force that controls what is happening. It watches over balance. It is thought that nudges you to see that something is wrong, that something needs to change. That something needs to be aligned within yourself.
Body. The lower form, but necessary for communication with the earth, with those who dwell in the lower realms. Those forces that always remain in the lower locations. But if reunited together, aligned in balance, you will attain liberation.
Or Ascension. As you wish."
"—So one pyramid is built into the other, like yin and yang? Balance. Thank you, Spirit."
