go near the element, look at it, feal it, talk with it.
if you wish to use elements in magick then:
fire - candles, other things where you put fire.
water - just water
air - chants, incense
earth - crystals, herbs, etc.
you can find your element on thinking about them and what is that you love the most and seem to respond(try to remember what have you done with the elements in your life)
I also believe in 6 elements, so the 2+ are light&dark
which does NOT mean good and evil. their just elements, among the others. :)
