If you care little about the results, or put only a small amount of energy into your desire, then you are unlikely to see any real results. The stronger the need or desire, then the more likely it is that you will raise the amount of energy required to bring about the change you seek. But desire or need is not enough. In the performance of magic, timing can mean success of failure. The best time to cast a spell or create a work of magic is when the target is most receptive.
Receptivity is assured when the target is passive.
One must also take into account the phase of the moon and the season of the year. Work with nature and not against it. The success of any work also depends upon images. Anything which serves to intensify the emotions will contribute to success. Any drawing, statue, photo, scent, article of clothing, sound or situation which helps to merge you with your desire will greatly add to your success.
