Know that the existence of all the world is generally divided into five parts: 1. Adam Kadmon [Primordial Man]; 2. Atzilut [Emanation]; 3. Beria [Creation]; 4.
Yetzira [Formation]; 5. Asiya [Action]. Each one of these worlds contains infinite details. They are aspects of the five Sefirot, “KaḤaV TuM”: Keter, Ḥokhma, Bina, Tiferet, and Malkhut.
That is to say, the world of Adam Kadmon is Keter; the world of Atzilut is Ḥokhma; the world of Beria is Bina; the world of Yetzira is Tiferet; and the world of Asiya is Malkhut. The lights that are enclothed in these five worlds are called YaḤNaRN (Yeḥida, Ḥaya, Neshama, Ruaḥ, Nefesh). The light of Yeḥida shines in the world of Adam Kadmon; the light of Ḥaya shines in the world of Atzilut; the light of Neshama shines in the world of Beria; the light of Ruaḥ shines in the world of Yetzira; and the light of Nefesh shines in the world of Asiya.
