I’ve always been attracted to general Witchcraft and I’ve been studying it more often lately because I notice that a knowledge of the craft is good for building blocks do more advanced rituals. Being around nature quite a bit growing up, I always had a deep want to understand the elements. I noticed that books geared towards Wiccan witches are actually great materials to study nature-based and elemental magic, partially because Wiccan rituals emphasize elemental powers, and partially because Wiccan rituals deal heavily with symbolism. Even though I have troubles with the philosophy of Wicca, the magic is somewhat helpful for me. I thought it would be helpful to share my version of the elements, which is partially dirived from the Wiccan system but with a more Mexican/Eastern/Chaotic twist.
EARTH
Earth is the element of wealth, stability, fertility and growth. Earth tends to be stubborn in the respect of wanting to be what it is, but if it is changed it still has the potential to do many wonders. Earth is symbolized by raw materials, and valuables like money. Its Zodiac signs are Taurus the bull, Virgo the virgin, and Capricorn the goat. It has attributes of the feminine. Earth compliments water, fed by fire, and feeds air. The colors of earth are green, brown and black.
WATER
Water is the element of health, change, life and healing. Water is creative and flows with ease, however it tends to carry contamination better than other elements, so it must be changed regularly. Water is symbolized by cups and caldrons. Its Zodiac signs are Cancer the crab, Scorpio the scorpion and Pieces the fishes. Like earth, it is a feminine element. Water moves earth, is moved by air and clashes rigorously with fire. The colors of water are blue, silver and gray.
AIR
Air is the element of wisdom, freedom, knowledge and journey. Air is stubborn like earth, but in the opposite respect of it refusing to not be on the move, so air never is truely still. Air is symbolized by blunt ritual tools, like wands and paper. Its Zodiac signs are Gemini the twins, Libra the scales and Aquarius the water-bearer. Air is an element with masculine qualities. Air moves water and earth easily but it must fight with fire to put it out, being damaged by the flame in the process. Air is represented by the colors yellow, white and pink.
FIRE
Fire is the element of passion, love, power and transformation. Fire is energetic and malleable like water, however it is the most destructive element, but often it will make way and feed the growth to come from its ashes. Fire is symbolized by sharp or burning tools, like candles and blades. Its Zodiac signs are Aries the ram, Leo the lion and Sagittarius the hunter. With air, fire harnesses masculine qualities. Fire burns air, feeds earth, and can either change or be changed by water. The colors of fire are red, gold and orange.
THE FIFTH ELEMENT
Sometimes a fifth element is in play. The Greeks eventually added Æther to their list of elements, describing it as the breath of the gods. The Tibetans have Space as element number five. In Wicca, the element is Spirit or (uncommonly) Akasha. But I would like to expand on what this element is and how you can incorporate it in your elemental magic.
The fifth element is essentially the element of life. All that lives, has lived and will live is a manifestation of the fifth element. The fifth element is all that is spiritual and intangible on the physical level. This also means it is the element of death, as death is just another fact of life, and life’s opposite within life itself. The fifth element is a cycle between what is and what isn’t. It is not good or evil, but amoral and balancing, yet unpredictable.
I like to call this element Chaos because all that exists comes from it, yet all is not Chaos. If you want to call it by another name, that’s fine. It will still have its attributes when known by another name. According to the Chinese primordial egg story, at one point, the world was only Chaos, until the first being Pangu separated it into duality, from which all other things are based upon. After he did so, he died from exhaustion and became the world. I think that represents the fifth element well in the form of the story, because the fifth element is the egg that creates everything. We don’t know what it is, but it’s around us and we can sense it. Chaos is the light and darkness that feeds and comes from all other elements.
Chaos is represented by purple, black and white, but it’s purest color is transparent. It can also be represented as living plants or something from a living thing. The yin-yang or any other duality symbol should capture the essence of Chaos well. Chaos creates and maintains all elements, which distribute order among themselves independent of Chaos.
Chaos can be hard to work with by itself, as it is an element of pure willpower. Because of this, Chaos is you. As long as you have will, you embody Chaos even beyond death.
I hope this helps or inspire others. Feel free to comment on this and add any details about or related to this.
