Start by learning the basics.
You can click on forums at the top and it will have a search bar on the forums page.
Some of the basics are: Meditation, Grounding, Centering, Visualization and energy manipulation.
More than 70 percent of the spells on here do not work. It is best that you become comfortable with the basics and perhaps write your own spells since they are more personal.
Never have anyone else cast a spell for you, it is more likely to work if you do it on your own.
