How to evoke the Elements
So that you can progress in rising to higher levels of your abilities, you should be a master in both evocation and invocation.
How to evoke Fire
Being in a trance, you visualize yourself in the middle of fire, feeling the heat, the burning, hearing the hissing of the flames. Begin to compress that fire into a space before you, that looks like a ball of fire. Pull the fire from all directions around you and squeeze it into the ball. You should feel hotter and hotter until having the feeling of being in an oven.
Now is the point where you let dissolve the ball of fire and visualize how it is dissipating. Keep on visualizing it disappearing, losing its power and heat, until it's gone.
How to evoke Air
Being in a trance, you visualize yourself in the middle of air. Pull the air simultaneously from all directions around you into a ball before you. By going on filling that ball of air, you should feel as light as having the feeling of floating.
Then you let dissolve it as you did with the ball of fire.
How to evoke Water
Being in a trance, you visualize yourself in the middle of the sea or a lake. Pull the water from all directions around you to your body. First, you should feel the water like a cold vapor. The closer you pull it to your body and compressing it, the colder you should feel it until finally, you should feel it icy cold.
Then you press it into a ball before you and let it dissolve as you did with the elements above until it's gone.
How to evoke Earth
Being in a trance, you pull a mass like clay simultaneously from all directions around you. Bring it closer and closer to you, while it is getting dark and brown, like soil. When you feel its pressure on your body, its heaviness, you visualize how you squeeze it into a ball in front of you. Let it dissolve as you already did with the other elements.
Try this one:
You evoke the element fire. Have a glass of tepid water before you. Pull the fire from all directions around you and condense it into the glass, while you imagine how the water is getting hotter and hotter.
The water's temperature will rise a few degrees if you are successful.
