The Divine mind of God, the Absolute, or in Hebrew the Ain Soph Aur (Limitless Light), through a series of expansions and contractions establishes the boundaries of Creation. The first world is the most subtle, and closest to the original state of non-existence, and is Atzilooth. This is called the world of Fire, because of the lively, undefined, and almost uncontrollable nature of fire. Next is Briah, or the World of Archetypes and forms as our human mind can grasp them. It is symbolized as the World of Air, and is the result as a barrier world that is formed by the creation of the next World, Yetzirah, or Water. This is the highly psychic and emotionally charged world immediately behind the veil of material existence, or Assiah. Also known as the World of Earth, because of the solid, concrete nature of material life.The purpose of this scheme, is to show that creation occurs in increasingly dense levels of energy-matter, from the most subtle, or Fire, to the most dense, or Earth. Within this context of increasing density, there also arises a series of ten planes or levels of consciousness which combines with energy-matter, known as Sepheroth, or spheres of being. They occur in a pattern of: unity, reflection, polarity, reflection, polarity, unity, reflection, polarity, unity, and finally materialization. This basic idea of unity-polarity-and re-harmonizing, is the basis of kabbalistic and alchemical practices, and is derived from the observation of Nature.
Each World is a reflection to a denser or more subtle degree than the one before or after it. Each Sepheroth is a reflection, in part, of what proceeds or follows it. However, since each reflection is only partial, or slightly distorted, each Sphere takes on its own unique characteristics. Only the so-called “Middle Four Sphereoth” have the ability to harmonize or reflect in total all of the energies of creation, on some level.
This ‘zigzag’ of Creation is called the “Lightning Flash”. The return of energy from dense matter, back through the various stages, Sepherith, and Worlds of Creation is known as the “Path of the Serpent” because of its reverse, or complimentary ‘zigzag’ nature back up this diagram called the Tree of Life.
For the alchemist, somewhere between the third and fourth level, or sphere of creation, energy takes on the characteristic that will allow for the formation of matter at some future state, or level ten. This energy is called Prima Materia, Chaos in the Bible, Spiritus Mundi (Spirit of the Earth), and others. Here, duality is made complete, and genuine polarity exists, as opposed to simple the potential, or idea, of polarity that had existed previously. Energy is divided into active and passive modes, with the active energy constituting the energies of life, and the passive one the energy of matter. In “The Golden Chain of Homer”, the active energy is called Niter and the passive energy is called Salt.
The energy of Life manifests in two forms, Fire and Air. While both are predominately active in nature, fire is the more active of the two, with Air being slightly passive because of the partial Water Element in its makeup. Potential Matter manifests its energy as Water and Earth. These Elements have nothing to do with the material bodies of the same name, and as such are capitalized and called “Elemental” to distinguish them from the earth we walk on, water we drink, air we breath, and fire we cook with. They are in fact, energetic states, each with their own unique characteristics, as well as each of the previously mentioned ten levels of consciousness within them. The Elements also have preferred ways of interacting with each other, to form the Three Principles of alchemy. There are in fact, forty different ways energy-matter-consciousness can manifest in our world.
The Three Essentials are the alchemical principles of Sulpher, Mercury, and Salt. Like the “Elements” these principle concepts are to be thought of a “Philosophical” and not literally as chemical elements or compounds. The Alchemical Sulphur, or Soul, of a things predominates in the animating principles of energy (Fire) and intelligence (Air); Alchemical Salt, or the physical body of a thing, predominates in unconscious forces, psychic, and instinctual intelligence (Water) and solid matter (Earth); Alchemical Mercury, or general life force, predominates in intelligence (Air) and instinctual forces, and psychic energy (Water), as such it is the link, or bridge, between the higher forces of Sulphur and the lower body of matter.
In the mineral realm the dominant energy is that of Earth, a little Water, and very little Air or Fire. In the vegetable realm, the dominant energy is Water and Air, but little Fire and Earth. In the animal realm, the dominant force element is Fire, then Air, but little Earth. These qualities need to be understood as they have been defined for the following information to be of any use to the practicing, or aspiring, Hermeticist. For example, using the above definitions, we can say that the plant realm has an abundance of instinctual energy (Water) and intelligence, i.e. a specific function (Air), but little direct energy (Fire), as this is received passively from the sun; and little hard, physical, matter (Earth).
In the East as in the West, the idea of principle Elements and Philosophic Principles are expressed in more or less the same manner. This original undifferentiated energy from creation is often called in Indian philosophy, and modern occult, and New Age circles, as akasha, or Spirit. However, akasha, consists of two (2) aspects, one active as we have noted, Niter, and the other passive, Salt. The energies of Niter are also referred to as the force of Kundalini, or spiritual forces. In alchemy, this is the Secret Fire. To the Salt, belongs the force of Prana, or Vital Energy.
The function of the Vital energy is to maintain physical life forms and existence. It is completely instinctual and unconscious and is heavily influenced by cosmic cycles, astrological pulses, and other natural phenomena. The function of the Secret Fire is to increase in humanity, the only place where it is present, its sense of self, or “I”. At the lowest level or functioning, this is the ego, at its highest, it is Divinity incarnate, as both are two sides of the same coin. One is ‘self’ in relation to the physical world and others; the other is ‘self’ in relationship to all of Creation and as a co-creator.
In the vast majority of humanity, this Secret Fire, or liberating energy of self-consciousness, lies dormant, asleep at the base of the spine, coiled like a serpent. Only a small amount manages to escape, reaching a sepherothic level, or so-called chakra, thus creating a loci of consciousness for each person. If it reaches the top of the skull, and beyond, a spiritual awakening can occur, allowing for a descent and re-ascent of the energy, during which the psychic centers can be awakened allowing for the manifestation of psychic powers and related phenomena.
The Secret Fire ascends as a result of a temporary weakening of the Vital Energy in the physical body. This is why so many spiritual awakenings take place under great physical stress, times of illness, or near-death-experiences. When the Secret Fire will ascend through the various psychic-physical currents causing it to be enveloped in a sphere of luminous light.
