This will also help to create the desired effect in the Witch. This is a more advanced idea, but it needs to be mentioned here quickly. Just as there are differences between stones and herbs, there are differences in people. Because of these different compositions in people, we are all tapped into a slightly different energy wavelength and this can cause variations in spellcasting methods. For example, one person on one wavelength may find that Rose Quartz works well for love, while another person on another wavelength may find it useful for attracting business success.
Witchcraft is a very positive, happy belief structure.
It is written directly in our code to harm no one. Unlike Christianity, we have no Satan. There is absolutely no purely negative creature in our beliefs. There is nothing that our ancestors have done to require us to request for forgiveness. We accept just about anyone into our belief structure.
