The four Worlds of Existence

The four Worlds of Existence:

World of Emanation
World of Creation
World of Formation
World of Action

World of Emanation / Fiery World / Azilut
The first stage of the manifestation of Existence (World of emanation) begins with the emergence of space out of NO-THING-NESS. The Absolute is withdrawing into ITSELF in order to allow existence to come into being. Into this void were emanated ten Devine Numbers / Devine Principles  (sefirot) which represented the major laws that were to govern all the worlds and their inhabitants. (see also Figures 23 & 24)

World of Creation / Airy World / Beriah
Then the spiritual level of Creation emerged. In a cosmic process Fire (light), Air, Water and Earth are organised into an ordered cosmos, in which three different levels of creatures can exist. The Bible tells that Adam was brought forth on the Sixt Day of Creation with the significant comment that "they" were created "in the image of god" - the spiritual Adam was a composite entity,  male and female. At this point all are still spiritual essences.

World of Formation / Watery World / Yezirah
Then comes the world of Formation or Eden. This is the realm of the soul. Here Eve, the female principle, was separated from the side of Adam. Eve was to be Adam's psychological complement or soul mate. The stories of Adam and Eve in the Garden Eden are mythological, which means that they describe important events prior to humanity's descent into matter. This is a clear statement that mankind pre-existed its terrestrial form. The fourth and lowest world of Action was brought into being on the Sixt Day of Creation but it is, at this point, as yet only a creative idea. The material realm only fully manifested later in form and matter.

World of Action / Earthly World / Asiyyah
Then comes the material world of Action after the Big Bang brought the physical universe into being. By putting on "coats of skin", as the bible states, Adam and Eve entered the lowest of the four worlds and become incarnate.

Only humans can enter and exist simultaneously in all the worlds. Natural and supernatural beings are confined to their respective realities. (What can an ape know of metaphysics or an angel understand about being in debt?)
