Bob to answer your question the three circles around the table are known as the Three Circles Of Existence as recorded in the Barddas: The first circle is Abred, the physical world where we live; The second Circle of Gwynedd, the blessed realm of the Otherworld; and the third Cicle of Ceugant, The Great Beyond, where none exist but God.
"We, the Shaman, stand upon the earth at the center of all--- the 1st Circle; the Caer Sidi, the sacred stone circle, exists as the Otherworld boundary all around us, the 2nd Circle; and beyond this, lies the Eternal ocean of the unknown, the 3rd Circle of Infinities."

Old Calendar: The Holy Guardian Angels
Each person on earth has a guardian angel who watches over him and helps him to attain his salvation. Angelical guardianship begins at the moment of birth; prior to this, the child is protected by the mother's guardian angel. This protection continues throughout our whole life and ceases only when our probation on earth ends, namely, at the moment of death. Our guardian angel accompanies our soul to purgatory or heaven, and becomes our coheir in the heavenly kingdom.
Angels are servants and messengers from God. "Angel" in Greek means messenger. In unseen ways the angels help us on our earthly pilgrimage by assisting us in work and study, helping us in temptation and protecting us from physical danger.
O Angel of God, to whose holy care I am committed by the supernal clemency, enlighten, protect, defend, and govern me. Amen.
"No evil shall befall you, nor shall affliction come near your tent, for to His Angels God has given command about you, that they guard you in all your ways. Upon their hands they will bear you up, lest you dash your foot against a stone." Psalm 91: 10-12
A heavenly spirit assigned by God to watch over each of us during our lives. The doctrine of angels is part of the Church's tradition. The role of the guardian angel is both to guide us to good thoughts, works and words, and to preserve us from evil.
Heavenly Father, Your infinite love for us has chosen a blessed angel in heaven and appointed him our guide during this earthly pilgrimage. Accept our thanks for so great ablessing. AMEN
