It is nice to have a way of communicating with your personal Guardian Angel, in ancient Greece this was referred to as your personal Demon, which shows that angels and demons were once one and the same. This is spoken about in some of the Apocryphal books of the bible and in christian myth.
According to legend Lucifer was the favourite angel of God and so had more leeway than other angels. However Lucifer got arrogant and decided he could take over from God and organised a band of rebel angels to seize power. God sent Michael as the head of his own army to battle the rebels and Michael won. Lucifer and all the rebels were cast out of heaven and consigned to the management of Hell.
Again according to legend you are allotted two spirits at birth, the guardian angel who whispers into your right ear and a little demon who whispers into your left ear. The angel is thought of as your conscience and the demon as the little voice that encourages you to be daring and naughty. These are, of course, ways of personifying concepts which can be difficult to explain otherwise - why you should choose to behave in a 'good' or 'bad' way.
There are four archangels which are associated with the elements and the four quarters of the magic circle. These four angels can therefore be used to create a protected area, which is the basic principle behind the well known magical ritual the Banishing Ritual of the Lesser Pentagram.
These four angels are:
Raphael the guardian of the east and angel of Elemental Air
Gabriel the western angel of Elemental Water
Uriel or Oriel who is the northern guardian and angel of Elemental Earth
And in the South Michael with a flaming sword, the guardian of Elemental Fire
You can create a very simple personal protection by saying aloud or in your head:
"Raphael before me, Gabriel behind me, Uriel on my left and
Michael on my right, guard me in your circle of fire."
You can create a gemstone angel circle too by using a stone for each of the elemental angels:
Agate for Raphael, Pear or coral for Gabriel, black agate or onyx or haematite for Uriel and red jasper or garnet for Michael. In the centre put a white candle and a stone to represent your personal guardian angel, I would suggest angelite or blue lace agate unless you have already chosen one which appeals to you. Then say something like:
Holy angels I ask that you imbue this stone with your power
and make it a special object to connect me with the
energy and vitality of my Holy Guardian Angel.
Sit and meditate for a few minutes and if possible leave the candle to burn down. Then take the centre stone and put it in a special pouch to carry with you.
Use it as soon as possible, simple say something like:
'Guardian angel here my plea
Safely guide and watch over me.'
