It is based on an old (often misinterpreted) piece of wisdom taught within the ancient mystery schools:
"Blessed in the man who consumes the beast within, so the beast becomes man. Cursed is the man that the beast cosume, so the man becomes beast"
A version of this is found in the Gospel of Thomas. Except it, like the majority of the Gospel of Thomas, has been horribly mistranslated:
7. Jesus said, "Lucky is the lion that the human will eat, so that the lion becomes human. And foul is the human that the lion will eat, and the lion still will become human."
It is about man (meaning mankind, male and female) overcoming their base primal instincts
It is one of the first stages of the process of initiation within the ancient mystery schools
In my tradition, they refer to this as "self-regulation" and it is a condition of being accepted as an initiate
"Self-regulation" is similar to what is described as the "40 days in the desert" in the Bible
In other historical texts, it is described as a period when famous initiates of the mystery schools "went to live in a cave", or "disappeared from the records for a few years"
In this process, we are made to withdraw from the world to the most extreme extent possible. To see if we are able to do so
The initial test is 40 days, and you have to give up everything and everyone
You are not allowed to see anyone. You are not allowed to go anywhere, unless it is unavoidable (buying food, etc)
You are not allowed to drink, smoke, do drugs
Any and all types of addictions or vices. Even coffee and sugar
If you can avoid you it, you are to cut off communication with the world completely. Talk to nobody. No sex. Nothing
The idea is to see if you are able to give everything up
Because later in the initiation process, you may very well lose everything and everyone you love. In order to make it impossible for such things to be used against you, to manipulate, coerce or control you
Even if it means sacrificing your wife, child, or even yourself, rather than be controlled
To begin with, you are tested to see if you can control your primal urges, addictions and vices. For a short period (40 days and nights)
More so, it is a test to see if you can emotionally regulate and balance yourself whilst isolated and deprived
This is the basis of the man consuming the beast within (slaying the Dragon)
This conditions you, to later being incorruptible, blameless and virtuous in you pursuits as an initiate of the mysteries
The later gateways of the mysteries to towards becoming what is referred to as one of the "illuminated" are designed to destroy those who attempt to seek them without a heart that is light as a feather, as in the Egyptian book of the dead (correct title "book of Illumination") which is actually a process you go through whilst you are alive, not when you die as is believed
The Cave represents internalisation. As with "initiation" meaning "To go into"
Opposite of this is the spiral cloud, which represents externalisation, referred to within the mysteries as "ascension", meaning "to go out from"
Scientifically today, we would correlate the internal "Dragon" to our internal layer primal "reptilian" brain
Overcome by the intelligence and civility of the outer externalised layers of the brain
The maiden represents the Meridian (Mary) which is the carrying forth of one torus/sphere of the philosophers stone to the other, in the same way that layered torus (Taurus, Horus, Torah) propagate within the processes of creation
Like the layers of all known creation. They get smaller, denser and more complex, exactly equal and opposite to them getting larger and opening, expanding outwards
This is "Initiation" and "Ascension"
The Meridian is the pathway of creation, which carries across the centre of the torus, throughout every layer, internal and external
Within the aspect of the knight and the dragon, it represents the "reason" for all that we do
Why should we go through all the effort to consume the beast within?
Because there is beauty within this world worth protecting
The maiden is a metaphor for the experience of everything that is beautiful
It is choosing LOVE over PAIN
It is choosing CREATION over DECAY
A simplified metaphor would be "the carrot on the stick" that keeps the animal moving forwards
The essence within the lesson, is to understand our potential for CREATION is equal to that of our potential for DECAY and destruction
It is easy for the man to become the beast
It is much harder for the beast to become the man
Such is the purpose of the mystery schools
To live ignorant within the mysteries is easy enough
Easy paths and religion are offered free and easy. They take no effort
The path of the illuminated is much harder
It needs be earned through sacrificing whatever is necessary. Everything and everyone you love, even if it means theirs or your own life
Because true understanding (the understanding of "self") can only come through experience
As with what you find with many people in forums such as this, they are well read on many things and have vast amounts of knowledge ... But without any real or true understanding of the things they think they know
Because they lack the experience
They are like people who may have seen a dragon or two slain, to know how it is done, but they have never done it themselves
A good example would be Australian Aboriginal culture, where the uninitiated are never supposed to speak on the rites, processes and things they have not personally been through and experienced themselves
In context of St George, they are still beasts. Not yet man
They have not traversed the dimensions in order to be able to perceive them
Hope this helps
