Same idea as the Aeons in Gnosticism. The first emanations of the One, the Monad.
“What you typically on your planet refer to as an Angelic energy, we can euphemistically say now, of course, this is in a sense a symbol, but we can euphemistically say that they are the next step down from all that is. The first split off from all that is are what you call Angelic consciousnesses. You understand the concept of all that is, what you typically call God? Yes. Well, you understand that everything is made of God? Therefore, everything in a sense is like a step down, taking the frequency and differentiating it and splitting it up into smaller and smaller and smaller pieces. The Angelic realm is the first step down from God, the first reflection of all that is into many reflections. That's what you call the Angelic level.” - Bashar
