Working with magical energy has two aspects. The first aspect is the creation of the energy. It can be created in a variety of ways, from certain rituals such as the classic Middle Pillar ritual or Watchtower ritual to sexual activity or breathing methods.
The second aspect is the control of the energy. Although the energy can be controlled by will alone, many other devices, from wands and daggers to talismans and amulets, may be used to direct energy. Undirected, the energy is free to expend itself without structure (as is seen in some poltergeist events). Directed, the energy can achieve the results that you desire. This, then, is one way magick works
