The above diagram shows the foundation of the MerKaBa in its non-spinning state. We all have fields of light around us like in this picture. While in a non-spinning state they do not perform their function properly just like a chakra that does not spin. The gateway to higher consciousness is closed and so the rest of the light body has trouble grounding and incarnating.
When the MerKaBa is activated it forms a counter-rotating field of light which creates a dimensional gateway for the light body to stabilize within the physical body and for its other structures such as the chakras to activate and stabilize as well. This allows for the possibility of incarnating higher consciousness permanently as well as raising the vibration of the physical body. If successful it becomes possible to take the physical body into the fourth dimension. In Hebrew, MerKaBa is spelt MerKaVa which means ‘Chariot’ and indeed that’s exactly what it is. It is a vehicle which can take you and your body between dimensions. Once raised into the fourth dimension the physical body will become much more subtle and may live for much longer. The possibility is also there to rise into even higher dimensions.
When the MerKaBa spins at a certain speed, a disk of light shoots out from the Base Chakra, in the perfect centre of the spinning star tetrahedron, to around 50-60 feet in diameter (illustrated above). This is what your activated MerKaBa would look like and in fact this field of light has an electro-magnetic component that can be seen with the appropriate instruments on a computer monitor.
The chakras, The Column and the MerKaBa are only a small part of the light body but they are the main structures that we will be working with. For spiritual transformation to occur, it is practice that is needed. You can study anatomy and biology all you like but until you do physical exercise your body will not become fit. Similarly, studying the structures of the light body will not awaken them. Practice will.
