Fire
Telepathy, consciousness (super-awareness of what's going on), mental clarity.
The fire sign is associated with Aries, Leo, and Sagittarius, all signs of leaders, go-getters, people who take the active role more often that receive a passive role. Hence, the element of fire imbues its holders with mental capabilities that soar over the rest i.e. telepathy, enhanced focus, etc. It is also the most masculine element of the four.
(Would you want a leader who wasn't clear-headed or, at the very least, influential?)
The communicative powers of the element of fire include the ability to bolster others minds, transferring consciousness (as in "possession"), immunity to fire and diseases, and, mostly importantly, a strong sense of love.
Water
Intuition
Water is related to the subconscious, the unknown known that's always accessible, but you just have to dive and search within. Intuition is defined as the "direct perception of truth, fact, etc., independent of any reasoning process; immediate apprehension." So if you are a Cancer, Scorpio or Pisces, you've probably noticed that it's very hard for people to bullshit you or try to to sell you something; you don't just walk right into something blindly without calculating in your head about every little thing your mind picks up. Immediately you can tell when a trap is imminent. It is the most feminine element of the four.
(As the most feminine element, remember how your mother was easily able to detect that something was wrong in a given situation, even when it wasn't verbally expressed?)
The communicative powers of Water include the ability to balance out the other elements, to create illusions, and to heal.
Air
Clairvoyance
Air is connected to clairvoyance, the ability to view reality from any angle. Gemini, Libra and Aquarius are of this element. Those in touch with the air element will be able to alter themselves easily to confront the issues they deal with in the world. It is the second most masculine element of the four.
(Have you ever met someone who had the foresight to prevent something terrible from happening?)
The communicative powers of Air are the ability to remote view, alchemy (the science of the soul), and shift frequency of their consciousness. These all relate to self-alchemy, which is someone's capacity to change their ways and view the world differently.
An example of self-alchemy would be Malcolm X, who's life views changed drastically at different stages of his life. If you read his autobiography, you'll realize at certain points of his life, he couldn't think or act a certain way anymore, simply because it didn't fit in with his goals at the given moment. That ability to drop habits and vocabulary at the drop of a hat is very difficult for some.
Earth
Psychometry
Finally, the last element: Earth. Associated with Taurus, Virgo and Capricorn, the Earth element is the most tactile of the four. It grants the ability of psychometry - the ability to pick up an object and instantly know everything about that object. (If you've seen the 1993 movie Meteor Man with Robert Townsend, you may remember one of the many abilities he gained was the ability to pick up magazines and instantly know everything inside.) It is the second most feminine element of the four.
(Have you ever gone shopping and just felt a certain item was made just for you?)
The communicative powers it grants include tapping into all of the other elements, talking to molecules, walking though rocks and woods, and delving deeper into the bodily senses.
Well there you have it. This is a small introduction of the elements, and as I said I plan to delve much deeper into this stuff because I'm very much interested. Stay tuned and learn more with me as I go along.
Anyways I'm tired of typing so Hotep to you all, and may you walk in the darkness, which is the light.
