I wouldn't get into magick to play with water and ice. What exactly is the point? Hours of concentration to maybe make a ripple in a cup? Magick isn't for parlor tricks. Is it possible to influence the elements with magick? Maybe, maybe not. But for what purpose? Magick is a way of life, an art. It is a way to better our lives and if we choose, the lives of others.
While others are healing, giving luck and protecting, you'll be staring at water and ice all day...doesn't seem very thrilling.
