What exactly does " Darkness is light, turned inside out" mean? what is the deeper notion concerned with this saying?
There is not only depth in this statement, but infinite depth. Beelzebul refers to some of the deepest alchemical realities in our universe, existence and world, going all the way up to the highest dimensions. And he manages to put this all in this small quote.
Due to English, the meaning is limited. But when I was translating this quote to other languages I found out the deepest essence. One day in communication, I heard him saying this in Ancient Greek and this revealed even more about the essence of the quote, something which blew my mind apart.
Beelzebul on a basic level wants to explain to human beings to stop worrying about the Darkness as it's an antithesis to the Light. Many people are falsely afraid of Darkness, or the "Dark Demons" and the related. That has arose out of an errant perception of that the origin of our world is indeed the "Darkness".
Darkness, should not be considered "evil" or "emptiness". It is neither. It is the dark force of the universe. We live in a dualistic universe where the qualities of male and female, darkness and light, are into an eternal form of interplay to teach us human beings a lesson.
Each interplay like Yin and Yang in creation. Without Darkness, light would never matter and therefore without darkness there would be no enlightenment. However, darkness would still exist without the light into a state solely by itself. Light could also likewise exist by itself.
Light for that matter is the power that comes from indeed discovering or gaining awareness of the darkness, because the darkness or the absence of light is the starting principal of the source of creation. In the Tarot, this is what the Hermit is doing, he is taking a lamp of limited light [that is on the shape of the geometry of the Heart Chakra] and piously and with humility goes on to embark into a journey to examine the darkness to expand his own consciousness.
For this reason, primordial entities like Atum were born in a dark universe that had nothing on it. Then, the Gods created light, the world and so on. But it was all created from and into darkness.
Lastly, the true essence of the darkness is meant to be turned inwards and outwards, in the never ending cycle of creation and infinite enlightenment. From this Beelzebul wants to show also the power of sacred geometry and infinite birth of the creative power, which constantly regenerates itself again and again ad infinitum, being the first and primordial cause of the Trine Power or "God" in permutation of the whole universe.
Internally for human beings, the more darkness exists, the greater the hope to achieve enlightenment. Where we normally should feel fear, we must dive into the darkness and absolve ourselves from the ignorance. The greater the ignorance, the better the prospect of enlightenment.
Indirectly, Beelzebul also tells the people to not be scared of the ignorance they now have [darkness] but rather, look at this as an opportunity to understand how much enlightenment they can receive too. And that is requires a change of mind, a flipping of a switch...
As a final note, there are even deeper messages in this quote, but another helpful thing to know would be that if one does what is called Ancient Greek "Metanoesis" which means "Transmutation of the soul/mind", and turning it "Inside out", ie, changing your perceptive by the root, to change our thoughts and our perspective of existence from the source of ignorance, pain and misery, for us to start birthing the opposite: light, power, understanding and wisdom and all the good qualities...
Darkness is light, turned inside out, after all...
HAIL BEELZEBUL!!
