Hello, miss lolabelle88.
Before we cast spells we must practice our basics, these basics are vital and must be done not only must they be done in the period of focus but also throughout the practitioners physical life. The basics do vary but most of the time there are
Mediation- the art of relaxing the brain to promote relaxation.
Visualization- seeing through the minds eye.
Correspondences- knowing what day,color,planet,time etc. To cast the spell on
Hope this helped, also there are a lot more basics I just named the ones that appear in most.
