Greetings Beautiful Oracle!
The primary reason for the existence of the Circle of Eight Oracles, is to assist each of us, to develop our Communion with our Holy Guardian Angel — our Spirit (see Figure 6 on Page 21 of Liber Aether).
At our first incarnation, we are each Divinely assigned a Guardian Angel, to watch over us for the duration of that, and all subsequent lifetimes. As we unfold from lifetime to lifetime, so too does our Guardian Angel, by association with us and our experiences. This Protective Angel is of the Ninth Order of the Celestial Hierarchy (see Figure 7 on Page 23 of Liber Aether) — the Lowest Order, generally called Angels or Malakhim — and is not the one we are referring to, as the Holy Guardian Angel. I had a lucid dream on Tuesday, 11 May 2010, and another on Wednesday, 23 November 2011, where I was contacted by my Guardian Angel. She gave me specific mystical training in the first one, and then completed it in the second one, as preparation for the work I am doing here now. On both occasions, she simply and specifically referred to herself, as a member of "The Ninth".
As a young child, I would sometimes awaken to find myself projected out of my body, and hovering outside my bedroom window. I would await, and soon I would sense the approach of a mighty, ancient, and wise Presence behind me. Then I would feel an increasingly powerful, penetrating vibration, at the Nape of my Neck, as it merged with me. This rhythmic vibration was a soundless (i.e. 7–8 Hz infrasound — see Figure 13 on Page 35 of Liber Aether), Ar-Arrr-Eee-Ooo-Mmm (see Figure 6 on Page 21 of Liber Aether and Edgar Cayce Reading 281-28). As I was in early childhood (i.e. 3 to 7 years of age), I thought it was Santa Claus, and I was in his invisible sleigh as he took me for a short journey, flying about the neighbourhood. In later life, I remembered these profound events, and eventually realised that I had made conscious contact with my Spirit — my Holy Guardian Angel — at my Alta Major Chakra, during these Astral Travelling experiences. This then is the Holy Guardian Angel we speak of, and they are the Divine part of ourselves, that was made in the Image of God, whose Form is our Spiritual Body, and whose Essence is our Monad (see Figure 6 on Page 21 of Liber Aether).
Thus, the Guardian Angel is a separate being, intimately associated with our Flame (i.e. Emotional Body), and looks after our Physical Body, while the Holy Guardian Angel is our Spirit (i.e. Spiritual Body), and looks after our Soul (i.e. Mental Body) (see Table 8 on Page 30 of Liber Aether). The structure of the Monad and its 12 Spirits, 144 Souls, and 288 Flames, are covered in Liber Aether (see Discussion of Figure 16 on Page 40 and Figure 16 on Page 41 of Liber Aether).
Blessings from the Eighth Oracle,
