Adam Kadmon is the first and innermost world, which precedes the four worlds of Atzilut (Emanation), Beria (Creation), Yetzira (Formation), and Asiya (Action). It incorporates all of existence, from its head, that is, the source, which is Ein Sof, to its lowest point, which is this physical world. This world is called Adam Kadmon because it is depicted in kabbalistic writings in the form of a man, having a head, body and appendages. Although all the worlds are likewise described in the form of a man, this world is the primeval one, before which there is no world, while the other worlds, which are external to it, are “mapped onto it,” lower manifestations of that primeval world: Atzilut, from the chest and below to the navel; and Beria, Yetzira, and Asiya, from the navel and below. This world corresponds to the sefira of Keter. Just as Keter itself is often regarded as above the sefirot, so too the world of Adam Kadmon is sometimes not considered part of the four worlds.
