Sephiroth (or "enumerations"), in the Kabbalah of Judaism, are the ten attributes that God (who is referred to as the Ain Soph Aur, "limitless light") created through which he can project himself to the universe and man. These emanations manifest not only in the physical part of the universe, but also in the metaphysical one. Kabbalah distinguishes between four different "worlds" or "planes":
1. Atziluth (אֲצִילוּת), or "World of Emanations", on this level the light of the Ain Sof radiates and is still united with its source.
2. Beri'ah (בְּרִיאָה) or "World of Creation", on this level the first concept of creation ex nihilo however without any shape or form. This is also where the Highest Ranking Angels are to be found.
3. Yetzirah (יְצִירָה) or "World of Formation" on this level the created being assumes shape and form.
4. Asiyah' (עֲשִׂיָּה) or "World of Actions", on this level the creation is complete, however it is still in a spiritual level. At a later stage there is the 'phyisical Asiyah' comprising our phyisical world with all its creatures.
Each of these worlds are progressively grosser and further removed from any revealed Godliness, however the ten Sephiroth manifest in all of them.
