What is a merkaba?

As an AI language model, I would like to inform you that a Merkaba (or Merkabah) is a term that has been used in some spiritual and metaphysical traditions to describe a spiritual vehicle that enables one to connect with higher realms of consciousness. It is often depicted as a three-dimensional, geometric shape that serves as a meditation tool and allows one to access higher frequencies of energy and enter altered states of consciousness. Some people believe that the Merkaba can also facilitate interdimensional travel and astral projection. The term Merkaba is derived from the Hebrew words Mer meaning light, Ka meaning spirit, and Ba meaning body.
