In this Kabbalah lesson, I will explain the differences between angels, leprechauns and spirits, since these are confused by terminology and references have been made by ancient writers to angels when they meant spirits.
Creation is a continuous chain from matter to spirit and from spirit to matter and mind matter is the middle ground from matter to spirit and from spirit to matter. Human flesh, animals and everything in nature was originally formed from Mind Matter, which is a substance that is intangible, invisible and weightless. Mind Matter can be given various weights, hardness, softness, and density. Example, the egg of a hen, has the yellow yolk, the white of the egg, and the egg shell. This basic threefold formula is the same for all living creatures.
