To be best suited with an element is called being "attuned" to an element. And there are two ways that i use to find out which element you are attuned to: Your birth sign (zodiac related), or you can go with the feelings test.
Each sign of the zodiac is given a general element which is 90% correct when one is trying to find out their element but there is still that 10% that this is incorrect for.
Each sign and their element goes as follows:
Water := Cancer , Scorpio , Pisces
Fire := Aries , Leo , Sagittarus
Earth := Taurus , Virgo , Capricorn
Wind := Gemini , Libra , Aquarius
Then we move on to the second method which requires more effort.
The feeling test is where you pay more attention tothe elements areound you and spread yourself through them and try to find which one you feel a strong pull to. Look back in your life and try to see which element has pulled to you the most. Then if still cant find out take it a step further.
Put all 4 elements infront of you and send your senses to them after you reach deep meditation then you will feel a strong pull from your attuned element.
The best items for this test are : a bowl of water, a small plate of dirt, a candle (lit), and an insent (lit).
An example of this could be (since ive done both tests) i am an aries so i am fire attuned, but i feel an equally strong pull to wind. And when i took the test i found out about my wind-type nature. ANd i found i am a Wind-Fire attuned being.
