Magic is the only secret to witchcraft. The practice of magic and spell casting dates back to ancient times. It was always dreaded and people feared the practice of it. The practice of witchcraft was considered evil and malicious and the witches who practiced witchcraft were killed one by one. They were usually burnt alive. However, of late times have changed and witches are free to practice witchcraft provided they do not harm the common masses.
Magic is a type of energy. This energy is suppressed within all people. However, spell casting and rituals are not the same. A different kind of energy is conjured when a witchcraft ritual is performed. As the rituals are performed, a lot of focus and concentration is required and spells are time consuming and elaborate. On the other hand spells are a lot easier to cast and are quicker. Nevertheless, the results of witchcraft rituals are perfect and successful most of the time and the chances of a ritual failing are very small. But there are greater possibilities of a spell casting to fail miserably and this happens due to several different reasons.
The reason why witchcraft is successful most times is that rituals take magic to a completely new level, which is strong and powerful. One has true knowledge of the divine deities in rituals and there is a strong connection, which helps making the magic or the witchcraft ritual successful and work most of the times. These rituals are very powerful and when it is performed in anger it can have horrible and devastating results. If one is using this to cause harm to another, though this is not recommended at all, there are chances that the result will backfire if performed in anger.
