2. The ability to form and visualize images and ideas in the mind, especially of things never seen or experienced directly. The imagination is an amazing and powerful part of our consciousness because it empowers our creativity – the actual ability to create. On the >a href="http://www.llewellyn.com/encyclopedia/term/tree+of+life">Tree of Life, imagination is found in Tiphareth as part of Ruach, the Conscious Self.
Imagination is the making of images, and magick is accomplished by making images and their movement real. Some of that reality comes in the process of charging those images with energy, but more comes by the acceptance of their reality on the astral plane. As images are charged in the astral world, they can be drawn into the physical world, or to have an effect on the physical plane.
