The word Merkaba is actually composed of three separate words: Mer, which means light, Ka, which means spirit and Ba, which means Body. Put together, these three words connote the union of spirit with the body, surrounded by light. The symbol, which takes the shape of a star, is believed to be a divine vehicle made entirely of light and designed to transport or connect the spirit and body to higher realms.
It is said that the symbol is composed of two-star tetrahedrons, which consists of counter-rotating fields of light and energy that surrounds each person. This energy extends beyond the body. Some believe that even planets have this Merkaba energy field around it.
Black obsidian is a glassy, silica-rich volcanic rock with an amorphous structure and a hardness of 5 to 5.5. The name is derived from the name of the prominent ancient Roman, Obsius. Black Obsidian powerfully eliminates negative energies in oneself and one’s environment. It is like a psychic vacuum cleaner, cleansing the auric field of disharmony, negative attachments, astral “junk,” as well as one’s own anger, greed, fear, resentment, etc.
