Why people hipe about it?
The video is self explanatory. According to wikipedia, the Hebrew word Merkabah (מרכבה "chariot", derived from the consonantal root r-k-b with general meaning "to ride") is used in Ezekiel (1:4-26) to refer to the throne-chariot of God, the four-wheeled vehicle driven by four "chayot" (Hebrew: "living creatures"), each of which has four wings and the four faces of a man, lion, ox, and eagle.
I have experience meditations of high context but unable to connect with this Merkabah, don't know if I am doing something wrong, or it just not for me. If you have any idea or experience with it, please post your comments. It will be interesting to know what others might experience.
