What you need-1 empty bowl
1cup of water
Focus
Patience
Close your eyes and imagine yourself surrounded by water, controlling it with your very own mind. Slowly open you eyes and poor some of the water into the bowl and say "Gods of earth, let me share with you the power to control water." Now poor some more of the water into the bowl and repeat the sentence. Continue doing this until the bowl is full and the cup is empty.
Make sure you are relaxed and alone while doing this.
